Chapter 2, Problem 44P

Consider each of the following molecules in turn: (a) dimethyl ether, ${\left({\text{CH}}_{\text{3}}\right)}_{\text{2}}\text{O}$; (b) trimethylamine, ${\left({\text{CH}}_{\text{3}}\right)}_{\text{2}}\text{N}$; (c) trimethylboron, ${\left({\text{CH}}_{\text{3}}\right)}_{\text{2}}\text{B}$; and (d) carbon dioxide $\left({\text{CO}}_2\right)$. Describe the hybridization state of the central atom (i.e., O, N, B, or C) of each molecule, tell what bond angles you would expect at the central atom, and state whether the molecule would have a dipole moment.
