Answer:C
Arrange the following compounds in increasing order of acid strength
A. (i) > (ii) > (iii) B. (ii) < (i) < (iii) C. (iii) < (i) < (ii) D. (iii) > (i) > (ii)
Explanation: The electron with drawing group (-NO2) increases the acid strength of aromatic acids while electron releasing group (-CH3) decreases the acid strength of aromatic acids. Hence, the increasing order of add strength is given as
