Question
Reactivity of 
with the following in the decreasing order is:
i) 
ii) 
iii) 
iv) 
- (i)>(ii)>(iii)>(iv)
- (iv)>(i)>(ii)>(iii)
- (i)>(iii)>(ii)>(iv)
- (iv)>(ii)>(iii)>(i)
The correct answer is: (iv)>(i)>(ii)>(iii)
The order of reactivity of G.R. with different functional groups is aliphatic aldehyde > aromatic > aldehyde >aliphatic ketone > aromatic ketone. Also, EWG favours NA reaction
iv.is aliphatic ketone with
effect of Ph group. 
(+R effect is not possible since the double bond of benzene ring is not in conjugation with (C=O) group. So, (iv) is the most reactive ketone
Hence, the order is
