Which one is the most reactive towards `S_(N)1` reaction ?

A

`C_(6)H_(5)CH_(2)Br`

B

`C_(6)H_(5)CH(C_(6)H_(5))Br`

C

`C_(6)H_(5)CH(CH_(3))Br`

D

`C_(6)H_(5)C(CH_(3))(C_(6)H_(5))Br`

Text Solution

Verified by Experts

The correct Answer is:
D
As `C_(6)H_(5)-overset(CH_(3))overset("| ")underset(C_(6)H_(5))underset("| ")(C^(+))` carbocation is most stable.
Therefore, `C_(6)H_(5)C(CH_(3))(C_(6)H_(5))Br` readily undergoes `S_(N)1` reaction.
