Question

Which of the following presents the correct order of the acidity in the given compounds?
A. `CH_(3)COOH gt BrCH_(2)COOH gt ClCH_(2)COOHgtFCH_(2)COOH`
B. `FCH_(2) COOH gt CH_(3)COOH gt BrCH_(2)COOHgtClCH_(2)COOH`
C. `BrCH_(2)COOH gt ClCH_(2)COOH gt FCH_(2)COOHgtCH_(3)COOH`
D. `FCH_(2)COOH gt ClCH_(2)COOH gt BrCH_(2)COOHgtCH_(3)COOH`

Answer 1

Correct Answer - D
The correct order of acidity in given compounds,
`FCH_(2)COOH gt ClCH_(2)COOH gt BrCH_(3)COOH gt CH_(3)COOH`
An electron withdrawing substituent stabilises the anion by dispersing the negative change and therefore increase the acidity.
