The weakest acid amongst the following is :
ClCH2COOH
HCOOH
FCH2CH2COOH
CH2(I)COOH
D.
CH2(I)COOH
The strength of carboxylic acid depends upon the nature of the electron withdrawing halogen atom. Greater the electron withdrawing influence of the halogen atom stronger will be the acid. The electron withdrawing effect of the halogen decreases as:
F > Cl > Br > I
Hence, CH2(I) · COOH is the weakest acid among these.
