Vedclass · Answer

(A) The cyclopentadienyl anion contains $6\pi$ electrons ($4n+2$ where $n=1$),which satisfies $H$ückel's rule for aromaticity. It is planar,cyclic,and fully conjugated,making it highly stable due to aromaticity.The allyl anion $(CH_2=CH-CH_2^-)$ is stabilized by resonance but is not aromatic.Since the cyclopentadienyl anion is aromatic,it is significantly more stable than the non-aromatic allyl anion. Thus,both the Assertion and the Reason are correct,and the Reason correctly explains the Assertion.

Assertion : Cyclopentadienyl anion is much more stable than allyl anion.
Reason : Cyclopentadienyl anion is aromatic in character.
