Vedclass · Answer

(B) $1$. $O_3$ (ozone) exhibits resonance,resulting in equal $O-O$ bond lengths due to partial double bond character. Thus,statement $A$ is correct.$2$. The thermal decomposition of $O_3$ into $O_2$ and $O$ is an exothermic process because the formation of the strong $O=O$ double bond releases more energy than is required to break the $O-O$ bonds in ozone. Thus,statement $B$ is incorrect.$3$. $O_3$ has all electrons paired,making it diamagnetic. Thus,statement $C$ is correct.$4$. $O_3$ has a bent (angular) molecular geometry due to the presence of a lone pair on the central oxygen atom. Thus,statement $D$ is correct.Therefore,the incorrect statement is $B$.

The incorrect statement$(s)$ about $O_3$ is (are):
