Question

Tell whether each of the following reactions is likely to be S_N1, S_N2, E1, E1cB or E2:

c) 

Step-by-Step Solution

Answer

c) The given reaction is S_N1 reaction.

S N 1 reaction

A S_N1 reaction is a two-step nucleophilic substitution reaction. It involves the loss of leaving group followed by the nucleophilic attack. The loss of leaving group generates carbocation.

Whether the reaction is S N 1, S N 2 , E1, E1cB or E2

c) The given reaction occurs by the S_N1 mechanism because the substrate of the reaction is tertiary, and we know that tertiary substrates form substitution products by  S_N1 route.
