Vedclass · Answer

(C) The enol content is determined by the stability of the resulting enol form. Aromaticity is a major factor in stabilizing the enol form.In option $(C)$,the first compound is the cyclopentadienyl anion derivative (cyclopent$-2-$en$-1-$one anion). Its enol form is the cyclopentadienyl anion,which is aromatic ($6 \pi$ electrons) and thus highly stable.The second compound is cyclopent$-2-$en$-1-$one,whose enol form is phenol (if it were a cyclohexadienone derivative) or a simple enol,which is significantly less stable than the aromatic anion formed from the first compound.Therefore,the second compound has less enol content than the first compound.

Among the given pairs,in which pair does the second compound have less enol content than the first compound?
