The Lewis structure for $\mathrm{O}_3$ molecule is given below. The correct formal charges on oxygen atoms labelled 1, 2, 3 are respectively.

1. –1, 0, + 1
2. +1, 0, – 1
3. +1, – 1, 0
4. 0, + 1, – 1

Solution

$\because \quad$ Formal charge $=$ No. of valency electron in central atom $-\left[\right.$ No. of lone pair $+\frac{1}{2}$ No. of bond pair of electron]
F.C for O labelled as $1=6-[6+1]=-1$ F.C for O labelled as $2=6-[4+2]=0$ F.C for O labelled as $3=6-[2+3]=+1$
