$KMnO_4$ does not act as an oxidising agent in an alkaline medium.

Vedclass · Answer

(D) $1$. Tungsten $(W)$ has the highest melting point among all metals due to strong metallic bonding,so statement $A$ is correct.$2$. Chromyl chloride $(CrO_2Cl_2)$ has a tetrahedral geometry around the central $Cr$ atom,so statement $B$ is correct.$3$. The yellow colour of $K_2CrO_4$ is due to the ligand-to-metal charge transfer $(LMCT)$ from $O^{2-}$ to $Cr^{6+}$,so statement $C$ is correct.$4$. $KMnO_4$ acts as a strong oxidising agent in acidic,neutral,and alkaline media. In an alkaline medium,it is reduced to manganate $(MnO_4^{2-})$,so statement $D$ is incorrect.
