Vedclass · Answer

(B) The cleavage of ethers with $HI$ involves the formation of an alkyl halide and an alcohol. In the case of alkyl aryl ethers,the bond between the oxygen and the alkyl group is cleaved because the bond between the oxygen and the aryl group has partial double bond character due to resonance,making it stronger and harder to break. However,diaryl ethers,where both groups attached to the oxygen are aryl groups,do not undergo cleavage by $HI$ even at high temperatures like $525 \ K$ because both $C-O$ bonds have partial double bond character. Option $B$ represents a diaryl ether,specifically $4-methylphenyl$ phenyl ether.

Which of the following aromatic ethers does not undergo cleavage by $HI$ at $525 \ K$?
