Q 11-11-20-P-c - Organic Chemistry (Mcmurry)

Question

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

Step-by-Step Solution

Answer

The given reaction is an E1cB reaction

E1cB reaction

An E1cB reaction 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 S N 1, S N 2, 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.
