Identify the major product P, Q and R in the following sequence of reactions:

Answer

D

Explanation

The given reaction takes place as follows :

Mechanism
Step I Formation of Carbocation
`CH_(3)CH_(2)CH_(2)-Cl+AlCl_(3) to CH_(3)CH_(2)overset(+)(CH_(2))+Aloverset(-)(Cl_(4))`
`underset((1^(@))underset("Carbocation")(CH_(3)CH_(2)overset(+)(CH_(2))) overset(1,2 H^(-) "shift")to underset((2^(@))underset("Carbocation")(CH_(3)overset(+)(CH)-CH_(3))`
Step II Electrophilic substitution reaction.

Step III Formation of peroxide

Step IV Hydrolysis of oxidised product formed in step III
