If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) Alkyl aryl ethers are cleaved at the alkyl-oxygen bond because the phenyl-oxygen bond has partial double bond character due to resonance,making it stronger and more stable.Therefore,the reaction of ethyl phenyl ether $(C_6H_5-O-C_2H_5)$ with $HBr$ proceeds as follows:$C_6H_5-O-C_2H_5 + HBr \rightarrow C_6H_5OH + C_2H_5Br$Both the Assertion and the Reason are correct,and the Reason correctly explains why the cleavage occurs at the alkyl-oxygen bond.

Assertion: Ethyl phenyl ether on reaction with $HBr$ forms phenol and ethyl bromide.
Reason: Cleavage of $C-O$ bond takes place at the ethyl-oxygen bond due to the more stable phenyl-oxygen bond.
