Vedclass · Answer

(A) The reaction of an alkyl aryl ether like ethoxybenzene $(C_6H_5OC_2H_5)$ with hot and concentrated $HI$ involves the cleavage of the $C-O$ bond between the alkyl group and the oxygen atom.This occurs because the $C-O$ bond between the phenyl ring and oxygen has partial double bond character due to resonance,making it stronger and harder to break.Therefore,the $HI$ attacks the alkyl group,resulting in the formation of phenol $(C_6H_5OH)$ and ethyl iodide $(C_2H_5I)$.

Identify the product obtained when ethoxybenzene reacts with hot and concentrated $HI$.
