Chapter 4, Problem 4.53E

Predict the shape of each of the following molecules by first drawing a Lewis strucuture, then applying the VSEPR theory:

a. ${\text{O}}_3$ (see Exercise $4.51$ for Lewis structure)

b. ${\text{SeO}}_2$ (see Exercise $4.51$ for Lewis structure)

c. ${\text{PH}}_3$ (each $\text{H}$ atom is bonded to the $\text{P}$ atom)

d. ${\text{SO}}_3$ (each $\text{O}$ atom is bonded to the $\text{S}$ atom)
