Which will undergo deprotonation most readily in basic medium?

Options

  1. Aa only
  2. Bc only
  3. CBoth a and c
  4. Db only

Correct answer

A. a only

Step-by-step solution

Due to the presence of two electron-withdrawing carbonyl group the methylene protons are very much acidic. The - M effect of - COCH 3 is more than - COOMe . Hence, the acidic nature of acetyl acetone is more than rest of the two molecules.
