Vedclass · Answer

(C) The acidity of a hydrocarbon depends on the stability of the conjugate base formed after the removal of a proton. For $Indene$ (option $C$),the removal of a proton from the $CH_2$ group results in the formation of an indenyl anion. This anion is aromatic because it contains $10 \ \pi$-electrons (following $H$ückel's rule,$4n+2$ where $n=2$),which provides significant stability. Since the conjugate base of $Indene$ is aromatic and highly stable,$Indene$ is the most acidic among the given hydrocarbons.

All the hydrocarbons shown are very weak acids. One,however,is far more acidic than the others. Which one is the strongest acid?
