When enolate A is compared with enolate B (A) (B) which of the following statements is true ?
A.A is more stable than B✓ Correct
B.B is more stable than A
C.A and B have the same stability
D.No comparison of stability can be made.
Explanation
In the enolate A, the negative charge can be delocalised over the two oxygen atoms and thus giving 2 canonical forms and hence is more stable. Therefore, the correct answer is option (a) A is more stable than B.
