Question

which is more acidic hydrogen
a 3 hexanone
b 2, 4 hexanedione
​c 2,5 hexanedione
​d 2, 3 hexanedione
​(pls explain completley every step how you got the answer)

Answer 1

2, 4-hexanedione (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. CH3−C||O−CH2−C||O−CH2CH32,4−Hexanedione−→−−OH−−H2OCH3−C||O−C−H−C||O−CH2CH3            CH3−C||O−C−H−C||O−CH2CH3↔CH3−C|O−=CH−C||O−CH2CH3 ↔CH3−C||O−CH=C|O−−CH2CH3

(I dont take the credit for this answer because its really ahead of my syllabus so i just browsed an answer for you. Hope it helps.)

Answer 2

Option b.....is the correct Answer
