Chapter 11: Q 11-11-20 P-b (page 347)

Tell whether each of the following reactions is likely to be SN1, SN2, E1, E1cB or E2:

b)

Short Answer

Expert verified

b) The given reaction is an E2 reaction

Step by step solution

01

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.

02

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.

An E2 reaction
