What is the hybridization for each of the indicated atoms in the following compound? A)I = sp²; II = sp²; III = sp². B)I = sp²; II = sp³; III = sp³. C)I = sp; II = sp²; III = sp³. D)I = sp²; II = sp²; III = sp³.

Question

Iodine (I) is bonded to 3 other atoms (2 carbon and 1 oxygen), which gives it a steric number of 3. In addition, it has one lone pair of electrons. This gives a hybridization of sp². Carbon (C) in the methyl group (II) is bonded to 3 other atoms (2 hydrogen and 1 iodine), which gives it a steric number of 3. It has no lone pairs, so the hybridization is sp². Carbon (C) in the phenyl group (III) is bonded to 4 other atoms (1 hydrogen, 1 iodine, 1 carbon, and 1 nitrogen), which gives it a steric number of 4. It has no lone pairs, so the hybridization is sp³.
