$CH_3-C\equiv N \rightarrow CH_3-\stackrel{\ominus}{C}=\stackrel{\oplus}{N}$

Vedclass · Answer

(C) The electromeric effect ($E$-effect) is a temporary effect involving the complete transfer of a shared pair of $\pi$-electrons to one of the atoms joined by a multiple bond at the request of an attacking reagent.In option $C$,the structure $CH_3-C\equiv N \rightarrow CH_3-\stackrel{\ominus}{C}=\stackrel{\oplus}{N}$ is incorrect because nitrogen is more electronegative than carbon.When the $\pi$-electrons of the $C\equiv N$ bond shift,they should shift towards the more electronegative nitrogen atom,resulting in $CH_3-\stackrel{\oplus}{C}=\stackrel{\ominus}{N}$.Therefore,the representation in option $C$ is wrong.

Which of the following electromeric effect representations is incorrect?
