Question

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

b)

Short answer

b) The given reaction is an E2 reaction

Step-by-step solution

E2 reaction

An E2 reaction occurs when a base attacks the beta hydrogen of an alkyl halide, which leads to the loss of leaving group.An E2 product formed is alkene.

Whether the reaction is SN1, SN2, E1, E1cB or E2

a) The given reaction occurs by an E2 mechanism because the substrate of the reaction is secondary halide, and it reacts with a strong base KOH. The product formed is an elimination product.
