A) (i) > (ii) > (iii) >(iv)
B) (ii) > (iv) > (iii) > (i)
C) (ii) > (iv) > (i) > (iii)
D) (ii), > (iii) > (iv) > (i)
Correct Answer: D
Solution :
(i) (ii) (iii) (iv) group at any position shows electron withdrawing effect thus acid strength is increased. But o-nitro benzoate ion is stabilised by intramolecular H-bonding, hence its acid strength is maximum, The effect is more at para position than meta. Thus, acid strength (II) > (III) > (IV) > (I)You need to login to perform this action.
