Vedclass · Answer

(C) The electromeric effect involves the complete transfer of a shared pair of $\pi$-electrons to one of the atoms joined by a multiple bond on the demand of an attacking reagent.In option $C$, the representation $-C \equiv N 	o -\mathop{C}\limits^{\ominus}=\mathop{N}\limits^{\ominus}$ is incorrect because it shows both atoms acquiring a negative charge, which is chemically impossible as the $\pi$-electrons must shift to one atom, leaving the other with a positive charge.The correct representation for the shift in a cyano group should be $-C \equiv N 	o -\mathop{C}\limits^{\oplus}=\mathop{N}\limits^{\ominus}$ because nitrogen is more electronegative than carbon.
