Question
Which molecule is nonlinear? (a) $\mathrm{SO}_{2} ;$ (b) $\mathrm{CO}_{2}$;(c) HCN; (d) NO.
Step 1
(a) $\mathrm{SO}_{2}$: The central atom, sulfur (S), has three electron groups around it - two oxygen atoms and one lone pair of electrons. The electron groups repel each other, causing the molecule to have a bent shape. Show more…
