Vedclass · Answer

(B) The acidity of a hydrocarbon is determined by the stability of its conjugate base. The more stable the conjugate base,the more acidic the hydrocarbon.Option $(B)$ represents cyclopentadiene. Upon losing a proton $(H^+)$,it forms the cyclopentadienyl anion,which contains $6 \pi$ electrons ($4n+2$ where $n=1$). This makes the conjugate base aromatic and thus highly stable.Other options do not form such stable aromatic conjugate bases upon deprotonation. Therefore,cyclopentadiene is the most acidic among the given compounds.
