Vedclass · Answer

(B) Electrical conductivity depends on the degree of dissociation of the acid. Stronger acids dissociate more,providing more ions in the solution. The acidity increases with the presence of electron-withdrawing groups due to the $-I$ effect. Difluoroacetic acid $(CHF_2COOH)$ has two fluorine atoms,which exert a stronger $-I$ effect compared to monofluoroacetic acid $(CH_2FCOOH)$,chloroacetic acid $(CH_2ClCOOH)$,or acetic acid $(CH_3COOH)$. Therefore,difluoroacetic acid is the strongest acid among the given options and will have the highest degree of dissociation,resulting in maximum electrical conductivity.

Which of the following aqueous solutions will have the maximum electrical conductivity?
