Vedclass · Answer

(C) Statement $I$ is correct: $Sn^{2+}$ is a reducing agent and $Pb^{4+}$ is a strong oxidising agent due to the inert pair effect.Statement $II$ is incorrect: Silicon exists as $[SiF_6]^{2-}$ but not as $[SiCl_6]^{2-}$ because the large size of $Cl^-$ ions makes the $[SiCl_6]^{2-}$ ion sterically unstable.Statement $III$ is incorrect: The hybridisation of carbon in fullerene is $sp^2$,as each carbon atom is bonded to three other carbon atoms.Statement $IV$ is incorrect: Among $Ge$,$Sn$,and $Pb$,the melting point order is $Ge > Sn > Pb$,so the lowest melting point is for $Pb$.Therefore,statements $II$,$III$,and $IV$ are incorrect. However,based on the provided options,the most appropriate choice is $II$ and $III$.
