Ether Cleavage reaction via substitution nucleophillic bimolecular reaction



The raection is an example of ether cleavage reaction. initial step is protonation. The lone pair on O are in  conjugation with the double bond. Due to this, this bond does not cleave here.after protonation, bromide  attacks from back side [an substitution nucleophillic bimolecular reaction].
 After sn2 reaction , the enol  formed tautomerises to keto form.
