The correct order of strengths of the carboxylic acids [I, II, III shown] is 1. II > III > I 2. III > II > I 3. II > I > III 4. I > II > III

Answer: 1. II > III > I Key idea: an electron-withdrawing atom near COOH stabilises the carboxylate and raises acidity; the effect weakens with distance. I (cyclohexane): no heteroatom, weakest acid. II: the ring O is bonded to the carbon next to the one carrying COOH, so its -I effect is strong; strongest acid. III: O is one carbon further away from the carbon carrying COOH, so the effect is weaker. Order: II > III > I.

Answer: 1. II > III > I

Key idea: an electron-withdrawing atom near COOH stabilises the carboxylate and raises acidity; the effect weakens with distance.

I (cyclohexane): no heteroatom, weakest acid.
II: the ring O is bonded to the carbon next to the one carrying COOH, so its -I effect is strong; strongest acid.
III: O is one carbon further away from the carbon carrying COOH, so the effect is weaker.

Order: II > III > I.
