Vedclass · Answer

(B) $NCl_5$ does not exist because nitrogen lacks vacant $d$-orbitals,whereas $PCl_5$ exists due to the presence of $d$-orbitals in phosphorus.$Pb$ exhibits the inert pair effect,which makes the $+2$ oxidation state more stable than the $+4$ state; therefore,$Pb$ prefers to form divalent compounds rather than tetravalent ones.In the $CO_3^{2-}$ ion,all three $C-O$ bonds are equivalent due to resonance.Both $O_2^{+}$ and $NO$ contain unpaired electrons in their molecular orbitals,making them paramagnetic.Thus,the statement in option $B$ is incorrect.
