it is not most number of acidic it is most acidic(not the quantity but the acidity of hydrogen)
Swarna Kamal Dhyawala ok ya got it !!!!!
Which of the following has the most acidic hydrogen?
(a) 3-hexanone
(b) 2,4-hexanedione
(c) 2,5-hexanedione
(d) 2.3-hexanedione
(b)2,4-hexadione
the answer must be 2,5 hexanedione
acidc hydrogen means hydrogen attached to the carbon atoms which directly attached to sp2 carbon atoms
In 2,4-hexadione if H+ is removed from carbon number 3 then it will cause delocalisation of electrons from oxygen on carbon number 2 to oxygen on carbon number 4
which will stabilise the carbanoin thus formed.This stabilization is the most in case of 2,4-hexadione.
