STANDARD Chemistry Acid Strength Multiple Correct Question
Which of the following is the correct order of acidity of carboxylic acids? (i) Cl₃CCOOH > Cl₂CHCOOH > ClCH₂COOH (ii) CH₃CH₂COOH > (CH₃)₂CHCOOH > (CH₃)₃CCOOH (iii) F₂CHCOOH > FCH₂COOH > ClCH₂COOH
(i) and (ii)
(ii) and (iii)
(i) and (iii)
(i), (ii) and (iii)
Correct Answer
Detailed Explanation
The strength of the acid increases with the inductive effect of the electronegative group attached to it (–I effect). The strength of the acid decreases with the presence of an electron-releasing group.
