- A$ONCl$ and $ONO^-$ are isoelectronic.
- B$O_3$ molecule is bent
- COzone is violet-black in solid state
- DOzone is diamagnetic gas.

Answer
$(a)$ Number of electrons in
$ \mathrm{ONCl}=3.2 \mathrm{e}^{-}$
$\mathrm{ONO}^{-}=24 \mathrm{e}^{-}$
Thus, $\ce{ONCl}$ and $\ce{ONO}-$ are not isoelectronic.
$(b) \mathrm{O}_{3}$ has bent shape structure. Central atom $O$ is $s p^{2}$ hybridised with $1$ lone pair of electrons.
$(c)$ Ozone is violet$-$black in solid state.
$(d) O_{3}$ has no unpaired electrons, thus it is diamagnetic.
