Text Solution
Verified by ExpertsThe correct answer is:
B
Phenol is most acidic of all the given compounds.
In phenol, the electron withdrawing phenyl ring polarizes the O—H bond thereby facilitating the release of 
as 
and hence phenol is most acidic.
In 
the electron withdrawingeffect of phenyl ring is somewhat diminished by the 
group and it is therefore less acidic than phenol. In and , −OH group is attached to alkyl groups which, due to their 
effect reduce the polarity of —OH bond and so the acidic strength is low.
