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) \[-N{{O}_{2}}\]group at any position shows electron withdrawing effect thus acid strength is increased. But o-nitro benzoate ion is stabilized by intramolecular H-bonding like forces hence its acid strength is maximum. Thus acid strength \[(II)>(III)>(IV)>(I)\]You need to login to perform this action.
