Correct option (b) 2,4-hexanedione
Explanation:
When \(\sum \mathrm{CH}_{2}\) group is surrounded by two electron withdrawing (electronegative) carbonyl groups then, it is most reactive and its both hydrogen atoms are acidic in character
Thus, \(\mathrm{CH}_{2} \mathrm{COCH}_{2} \mathrm{COCH}_{2} \mathrm{CH}_{3}(2,4\)-hexanedione \()\) is one of the reactive methylene compounds.
