MOLECULAR SHAPES</h2>
<ul>
<li>Properties of molecular substances depend on the structure of the molecule. The structure includes many factors:</li>
<li>The skeletal arrangement of the atoms</li>
<li>The kind of bonding between the atoms (ionic, polar covalent, or nonpolar covalent)</li>
<li>The shape of the molecule</li>
<li>Bonding theory allows us to predict the shapes of molecules. Molecules are threedimensional objects. We often describe the shape of a molecule with terms that relate to geometric figures.</li>
<li>These geometric figures have characteristic &quot;corners&quot; that indicate the positions of the surrounding atoms around a central atom in the center of the geometric figure. The geometric figures also have characteristic angles that we call bond angles.</li>
<li>Lewis theory predicts regions of electrons in an atom. Some regions result from placing shared pairs of valence electrons between bonding nuclei. Other regions result from placing unshared valence electrons on a single nuclei.</li>
<li>Lewis theory states that these regions of electron groups should repel each other, because they are regions of negative charge. This idea can then be extended to predict the shapes of the molecules.</li>
<li>The position of atoms surrounding a central atom will be determined by where the bonding electron groups are. The positions of the electron groups will be determined by trying to minimize repulsions between them.<br />

<h2 type="section" data-unnumbered="true" id="vsepr-theory" class="section-title">
VSEPR THEORY</h2>
<ul>
<li>Electron groups around the central atom will be most stable when they are as far apart as possible. We call this valence shell electron pair repulsion (VSEPR) theory.</li>
<li>Because electrons are negatively charged, they should be most stable when they are separated as much as possible. The resulting geometric arrangement will allow us to predict the shapes and bond angles in the molecule.</li>
<li>The Lewis structure predicts the number of valence electron pairs around the central atom(s). Each lone pair of electrons constitutes one electron group on a central atom. Each bond constitutes one electron group on a central atom, regardless of whether it is single, double, or triple.<br />
<figure style="text-align: center"><img src="https://cdn.mathpix.com/cropped/4e6b81a0-645b-4565-b1ab-92aa044eb00a-02.jpg?height=106&amp;width=331&amp;top_left_y=958&amp;top_left_x=999" alt="" data-align="center" /></figure></li>
<li>Based on VSEPR, there are five basic electron-pair geometries. The actual geometry of the molecule might be different from these if one or more of the electron pairs are lone pairs. The 3 electron-pair geometries discussed earlier are listed below.</li>

GEOMETRIES WITH FIVE &amp; SIX ELECTRON-PAIR GROUPS</h2>
<ul>
<li>When there are five electron groups around the central atom, they will occupy positions in the shape of two tetrahedra that are base to base with the central atom in the center of the shared bases. This results in the electron groups taking a trigonal bipyramidal geometry.<br />

<li>When there are six electron groups around the central atom, they will occupy positions in the shape of two square-base pyramids that are base-to-base with the central atom in the center of the shared bases. This results in the electron groups taking an octahedral geometry. This shape is called octahedral because the geometric figure has eight sides.<br />

<li>Lone pairs also affect the molecular geometry. They occupy space on the central atom, but are not &quot;seen&quot; as points on the molecular geometry.</li>
<li>Lone pair groups &quot;occupy more space&quot; on the central atom because their electron density is exclusively on the central atom, rather than shared, like bonding electron groups. The bonding electrons are shared by two atoms, so some of the negative charge is removed from the central atom.</li>
<li>Relative sizes of repulsive force interactions is as follows:<br />

SUMMARIZING VSEPR THEORY</h2>
<ul>
<li>The geometry of a molecule is determined by the number of electron-pair groups on the central atom (or the interior atoms, if there is more than one central atom).</li>
<li>The number of electron-pair groups is determined from the Lewis structure of the molecule. If the Lewis structure contains resonance structures, use any of the resonance structures to determine the number of electron-pair groups.</li>
<li>Each of the following count as one electron-pair group: lone pair, a single bond, a double bond, a triple bond, or a single electron (as in a free radical).</li>
<li>The geometry of the electron-pair groups is determined by their repulsions as summarized in Table 10.1. In general, electron-pair groups repulsions vary as follows:</li>
</ul>
<div>Lone pair-lone pair &gt; lone pair-bonding pair &gt; bonding pair-bonding pair</div>
<ul>
<li>Bond angles can vary from the idealized angles because double and triple bonds occupy more space than single bonds (they are bulkier even though they are shorter), and lone pair occupy more space than bonding pairs. The presence of lone pairs usually makes bond angles smaller than the ideal angle for the particular geometry.</li>
</ul>
<h2 type="section" data-unnumbered="true" id="examples%3A" class="section-title">
Examples:</h2>

<li>Suppose that a molecule with six electron-pair groups were confined to two dimensions and therefore had a hexangonal planar electron-pair geometry (shown on the right). If two of the six groups were lone pairs, where would they be located? Why?<br />

<li>Larger molecules may have two or more interior atoms. When predicting the shape of these molecules, apply the principles discussed to each interior atom.</li>
<li>For example, glycine, an amino acid found in many proteins, contains four interior atoms: one N , two C 's, and an O atom. To determine the shape of glycine, the shape about each interior atom is determined as follows:<br />

MOLECULAR SHAPE AND POLARITY</h2>
<ul>
<li>Earlier we discussed polar bond. Entire molecules can also be polar, depending on their shape and the nature of their bonds. For example, if a diatomic molecule has a polar bond, the molecule as a whole would be polar.<br />

<li>In polyatomic molecules, presence of polar bonds may or may not result in a polar molecule, depending on the molecular geometry. If the molecular geometry is such that the dipole moments of individual polar bonds sum together to a net dipole moment, then the molecule will be polar. But if the molecular geometry is such that the dipole moments of the individual polar bonds cancel each other and sum to zero, then the molecule will be nonpolar.</li>

VALENCE BOND THEORY</h2>
<ul>
<li>In the Lewis model, &quot;dots&quot; are used to represent electrons as they are transferred or shared between bonding atoms. Based on quantum mechanical theory, however, such a treatment is oversimplification.</li>
<li>More advance bonding theories treat electrons in a quantum mechanical manner, and are actually extensions of quantum mechanics, applied to molecules. One such theory is the valence bond (VB) theory. A quantitative treatment of this theory is not the scope of this course. However, a qualitative description of the theory is discussed in this section.</li>
<li>According to valence bond theory, electrons reside in quantum mechanical orbitals localized on individual atoms. In many cases, these orbitals are the standard s, p, d, and f orbitals we discussed earlier in Chapter 7. In other cases, these orbitals are hybridized atomic orbitals, a kind of blend or combination of two or more standard orbitals.</li>
<li>When two atoms approach each other, the electrons and nucleus of one atom interact with the electrons and nucleus of the other atom. In VB theory, the effect of these interactions on the energies of the electrons are calculated. If the energy of the system is lowered because of the interactions, then the chemical bond is formed. If the energy of the system is raised by the interactions, then the chemical bond does not form.</li>
<li>For example, as the diagram below shows, the potential energy of two hydrogen atoms is lowest when they are separated by a distance that allows their 1s orbitals substantial overlap without too much repulsion between their nuclei. This distance, at which the system is most stable, is the bond length of the <span class="math-inline ">

<li>When the concepts of VB theory are applied to a number of atoms and their corresponding molecules, the following general observation is found:</li>
<li>The interaction energy is usually negative (or stabilizing) when the interacting atomic orbitals contain a total of two electrons (oriented with opposing spins).</li>
<li>Most commonly, the two electrons come from two half-filled orbitals, but in some cases, the two electrons come from one filled orbital overlapping with a completely empty orbital (called coordinate covalent bond).</li>

<li>Hybridization is a mathematical procedure in which the standard atomic orbitals are combined to form new atomic orbitals, called hybrid orbitals, that correspond more closely to the actual distribution of electrons in chemically bonded atoms.</li>
<li>Hybrid orbitals are still localized on individual atoms, but they have different shapes and energies from those of standard atomic orbitals. In hybrid orbitals, the electron probability density is more concentrated in a single directional lobe, allowing greater overlap with the orbitals of other atoms.</li>
<li>In VB theory, the chemical bond is the overlap of two orbitals that together contain two electrons. The greater the overlap, the stronger the bond and the lower the energy.</li>
<li>The mathematical procedure for obtaining hybrid orbitals is beyond the scope of this course. However, the following general statements can be made regarding hybridization:</li>
<li>The number of atomic orbitals added together always equals the number of hybrid orbitals formed. The total number of orbitals is conserved.</li>
<li>The particular combination of standard atomic orbitals added together determines the shapes and energies of the hybrid orbitals.</li>
