Type: MCQ-conceptual-Medium-Class 11
Which of the following represents the correct order of the acidity in the given compounds? FCH₂COOH > CH₃COOH > BrCH₂COOH > ClCH₂COOH
A
FCH₂COOH > CH₃COOH > BrCH₂COOH > ClCH₂COOH
B
BrCH₂COOH > ClCH₂COOH > FCH₂COOH > CH₃COOH
C
FCH₂COOH > ClCH₂COOH > BrCH₂COOH > CH₃COOH
D
CH₃COOH > BrCH₂COOH > ClCH₂COOH > FCH₂COOH
Correct Answer
Option c
Detailed Explanation
The acidity increases with the electronegativity of the substituent. Fluorine being the most electronegative, makes FCH₂COOH the most acidic.
