For the following compounds, the correct statement(s) with respect to nucleophilic substitution reactions is(are)

I and III follow S N 1 mechanism

I and II follow S N 2 mechanism

Compound IV undergoes inversion of configuration

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION.

(a, b, c, d)

Benzylic and 3° halides both follow S N 1 mechanism.

Benzylic and 1° halides both follow S N 2 mechanism.

Benzylic 2° halides can undergo inversion of configuration.

The order of reactivity would be IV > I > III if both S N 1 and S N 2 are considered suitably for substrates.
