Vedclass · Answer

(A) In the resonance structure of ozone $(O_3)$: $1$. The central oxygen atom has $1$ lone pair. $2$. The terminal oxygen atom with the double bond has $2$ lone pairs. $3$. The terminal oxygen atom with the single bond has $3$ lone pairs. Total number of lone pairs $= 1 + 2 + 3 = 6$. Total number of bond pairs (counting each bond as one pair) $= 3$ (one double bond counts as $2$ bond pairs and one single bond counts as $1$ bond pair). Ratio of lone pairs to bond pairs $= 6:3 = 2:1$.

List-$I$ (Species)	List-$II$ (Number of lone pairs)
$A. \ CH_3COCH_3$	$I. \ 2$
$B. \ CH_3CO^+$	$II. \ 0$
$C. \ CH_3CH_2^+$	$III. \ 1$
	$IV. \ 3$
