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 $-C \equiv N 	o -\mathop{C}\limits^{\oplus}=\mathop{N}\limits^{\ominus}$ is incorrect because the electronegativity of nitrogen is higher than that of carbon. Therefore,the $\pi$-electrons should shift towards the nitrogen atom,resulting in a positive charge on carbon and a negative charge on nitrogen. The correct representation should be $-C \equiv N 	o -\mathop{C}\limits^{\oplus}=\mathop{N}\limits^{\ominus}$ is actually correct,but let's re-evaluate: The shift should be $-C \equiv N 	o -\mathop{C}\limits^{\oplus}=\mathop{N}\limits^{\ominus}$ is correct. Wait,looking at the options,option $C$ shows $-C \equiv N 	o -\mathop{C}\limits^{\ominus}=\mathop{N}\limits^{\ominus}$,which is chemically impossible as both atoms cannot have negative charges simultaneously in this displacement. Thus,$C$ is the incorrect representation.
