Chapter 14, Problem 28E

Many important compounds in the chemical industry are derivatives of ethylene ${\text{(C}}_{\text{2}}{\text{H}}_{\text{4}}\text{)}$ . Two of them are acrylonitrile and methyl methacrylate.

Complete the Lewis structures for these molecules, showing all lone pairs. Give approximate values for bond angles $\text{a}$ through $\text{f}$ , and give the hybridization of all carbon atoms. In acrylonitrile and methyl methacrylate indicate which atoms in each molecule must lie in the same plane. How many $\text{σ}$ bonds and how many $\text{π}$ bonds are there in acrylonitrile and methyl methacrylate?
