(D) To determine the presence of $\pi$ bonds,we examine the Lewis structures of the given molecules:$1$. $SO_2$: The structure is $O=S=O$ (with a lone pair on $S$),containing two $\pi$ bonds.$2$. $NO_2$: The structure involves a nitrogen atom with an unpaired electron and double bonds,containing $\pi$ bonds.$3$. $CO_2$: The structure is $O=C=O$,containing two $\pi$ bonds.$4$. $H_2O$: The structure is $H-O-H$ with two lone pairs on the oxygen atom. All bonds are $\sigma$ bonds. There are no $\pi$ bonds in the $H_2O$ molecule.Therefore,the correct option is $D$.

Which one of the following molecules contains no $\pi$ bond?
