Vedclass · Answer

(C) The acid strength depends on the stability of the conjugate base formed after the loss of $H^+$ ion.Electron-withdrawing groups ($-I$ effect) stabilize the carboxylate anion,thereby increasing acidity.Fluorine $(F)$ has a stronger $-I$ effect than Chlorine $(Cl)$.Therefore,trifluoroacetic acid $(CF_3COOH)$ is a stronger acid than trichloroacetic acid $(CCl_3COOH)$.Formic acid $(HCOOH)$ is stronger than acetic acid $(CH_3COOH)$ because the methyl group in acetic acid exerts a $+I$ effect,which destabilizes the carboxylate anion.The order of decreasing acid strength is: Trifluoroacetic acid $(2)$ $>$ Trichloroacetic acid $(1)$ $>$ Formic acid $(4)$ $>$ Acetic acid $(3)$.Thus,the correct order is $2 > 1 > 4 > 3$.

The correct order of decreasing acid strength of the following acids is:
$(1)$ Trichloroacetic acid
$(2)$ Trifluoroacetic acid
$(3)$ Acetic acid
$(4)$ Formic acid
