Choose an option
Show full solutionCorrect option: A
Step-by-step explanation
Relation with HBr to give phenol
(1) 
The reaction involves two steps,
) The lone pair of oxygen atom attacks on the hydrogen of HBr.
) The nucleophile Br attacks on the methyl group which lead to the formation of phenol along with methyl bromide.
Phenol is formed from this compound on reaction with HBr.
(2) 
No phenol formation in this case because alkyl chain is attached to the benzene ring and on addition of H-Br, either H or Br get attached to this chain and no OH group is formed as it is directly bonded to the benzene ring.
(3) 
No phenol formation in this case. OH group is formed as
So, phenol product is formed in case of option (1) compound only.
