Draw the Lewis structures for the following molecules. For each molecule, determine its (a) electronic geometry, (b) number of nonbonding domains on the central atom, and (c) polarity of the molecule. Remember, that molecules that have zero nonbonding domains on the central atom AND have all of the outer atoms the same are NONPOLAR.
Generally, molecules with different outer atoms or with more than one nonbonding domain are POLAR. However, these may be NONPOLAR ONLY IF the dipoles cancel each other due to a symmetrical arrangement.
SO2 (a) electronic geometry: (b) number of nonbonding domains on central atom: (c) molecule polarity: BCl3 (a) electronic geometry: (b) number of nonbonding domains on central atom: (c) molecule polarity:
OF2 (a) electronic geometry: (b) number of nonbonding domains on central atom: (c) molecule polarity: ClF3 (a) electronic geometry: (b) number of nonbonding domains on central atom: (c) molecule polarity:
