Ans : null ()

The +I effect of -CH₃ group increases the electron density on the O-H bond. Therefore, release of proton becomes difficult. On the other hand, the -I effect of F decreases the electron density on the O-H bond. Therefore, proton can be released easily. Hence, CH₂FCO₂H is a stronger acid than CH₃CO₂H.

F has stronger -I effect than Cl. Therefore, CH₂FCO₂H can release proton more easily than CH₂ClCO₂H. Hence, CH₂FCO₂H is stronger acid than CH₂ClCO₂H.
