Ethyl ester `overset(MeMgBr) underset(excess)rarr P`. The product `P` will be :

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
Ester react with excess of Griganard to form `3^(@)` alcohol having at least two identical alkyl groups corresponding to Grignard reagent.

Sincehere Grignard reagent is `CH_(3)MgBr`the `3^(@)` alcohol should have at least two methyl groups.
Thus, the choice with at least two methyl groupa at the carbon linked with `-OH` group will be the correct choice. Hence (a) is the correct choice.
