Which of the following option is correct about ${\mathrm{NO}}_2$ and ${\mathrm{ClO}}_2$?

${\mathrm{NO}}_2$ is ${\mathrm{sp}}^2$ hybridized

It has 1 unpaired electron, so paramagnetic shape of ${\mathrm{NO}}_2$ is bent and it dimerizes easily.

${\mathrm{ClO}}_2$ has ${\mathrm{sp}}^2$ hybridization

and the  ${\mathrm{ClO}}_2$ and is bent shape and ${\mathrm{ClO}}_2$ do not dimerize because ${\mathrm{ClO}}_2$ has vacant d-orbital.

Hence, the correct option is B.
