Reactions of `C_(6)H_(5)CH_(2)Br` with aqueous sodium hydroxide follows……..

Options

A. `S_(N_(2)^(1))` mechanism
B. `S_(N^(2))` mechanism
C. Any of the above two depending upon the temperature of reaction
D. Saytzeffrule

Answer

A

Explanation

`C_(6)H_(5)CH_(2)Br` will follow `S_(N)1` mechanism on reaction,with aqueous sodium hydroxide since the carbocation formed `C_(6)H_(5)CH_(2)` is resonance stabilized cation.
Benzylic halides show high reactivity towards the `S_(N)1` reaction.The carbocation thus formed gets stabilized through resonance as shown in the structure.
