Which of the following has the most acidic hydrogen ?

Options

A. 3-hexanone
B. 2, 4-hexanedione
C. 2, 5-hexanedione
D. 2, 3-hexanedione

Answer

B

Explanation

Out of the four options given 2, 4-hexadione (a 1, 3-diketone) has the most acidic hydrogen. This is because the carbanion left after the removal of `H^(+)` is resonance stabilised in this case.
