$IV$

Vedclass · Answer

(D) Resonating structures involve the delocalization of $\pi$-electrons or lone pairs,but they do not involve the movement of atoms or groups of atoms. In structures $I$,$II$,and $III$,the connectivity of atoms remains the same,and only the positions of electrons change. In structure $IV$,the negative charge is on the terminal carbon atom,which implies a different connectivity compared to the enolate structures $I$,$II$,and $III$. Thus,structure $IV$ is not a resonating structure of the others.

Among the following structures,the one which is not a resonating structure of others is:
