Question

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

Short answer

The given reaction is an E1cBreaction

Step-by-step solution

E1cB reaction

An E1cBreaction is a type of elimination reaction that requires basic conditions.The leaving group is a relatively poor one, and the hydrogen to be removed is somewhat acidic.

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

d) The given reaction occurs by an E1cB mechanism because the leaving group is present at two carbons away from the carbonyl functional group.
