Fluoroacetic acid is stronger than chloroacetic acid. Explain why ?

Text Solution

Verified by Experts


Electron withdrawing group (EWG) i.e. -I effect stabilizes the carboxylate ion by dispersing the negative charge and hence increase the acidity of carboxylic acid. Now a F is more electronegative than Cl. So it has more tendency of electron attracting. That.s why flouroacetic acid is stronger acid than chloroacetic acids As greater is number of the electronegative atoms, greater is dispersion of negative charge. Decreasing order :
`FCH_2 COOH gt CICH_2 COOH gt BrCH_2 COOH gt ICH_2 COOH`
