Question

The correct order of increasing acid strength of the compounds is (a) CH 3 ​ CO 2 ​ H (b) MeOCH 2 ​ CO 2 ​ H (c) CF 3 ​ CO 2 ​ H (d) C H 3 ​ C H ( C H 3 ​ ) C O 2 ​ H

TestHub · Accepted Answer

Acid strength increases with electron-withdrawing groups (EWG) and decreases with electron-donating groups (EDG).

The order of increasing acid strength is:

$C H_{3} C H (C H_{3}) C O_{2} H$ (strongest EDG) < $C H_{3} C O_{2} H$ < $M e OC H_{2} C O_{2} H$ (weak EWG) < $C F_{3} C O_{2} H$ (strongest EWG).
