Question

pls answer the question with proper explaination​

Answer 1

Hi

The method of solving such questions is by seeing the position and function of the group

Here we have 2 functional groups Ketone and Ester groups

• Ketone : - Has -I effect that is it is an electron deficient group and it withdraws the electron near it , thus increasing the acidity.
• Ester : - Has +I effect that is it is an electron rich group and it gives of the electron from electron rich oxygen, thus decreasing acidity.

Thus we can easily say that the option having 2 Ketone groups would have the most acidic H, which is between the 2 -CO- groups.

Thank You!

Hope You Have Understood.
