    Chloroacetic acid is stronger than acetic acid because of the electron-withdrawing effect of chlorine.

    ok sir ...

    eduncle-logo-app

    sir acidity means tendency to donate h+

    eduncle-logo-app

    yes

    eduncle-logo-app

    After donation anion must be stable

    and basiscitu means tendency to donate electrons

    eduncle-logo-app

    how

    eduncle-logo-app

    what is ( c) compound?

    eduncle-logo-app

    1hydroxy ethanoic acid

    eduncle-logo-app

    see shweta..chlorine is EWG and also electronegative so it increases acidic character...also OH group acts as EWG only due to the electronegative nature of oxygen

    eduncle-logo-app

    and if hydroxyl group is attached to alkyl chain then it acts as EWG but if attached to aromatic rings then it acts as a EDG

    eduncle-logo-app

    ok

    eduncle-logo-app

    c kyun ni hai

    eduncle-logo-app

    acidic

    eduncle-logo-app

    but here b is more acidic...here EWG nature of Cl dominates.... also Pka values of glycolic acid(2-hydroxyethanoic acid ) is 3.83 and pka value of chloroacetic acid is 2.86...you know more the pka value less the acidity...So here option B is most acidic among these

    eduncle-logo-app

    got shweta??

    eduncle-logo-app

    ok

    eduncle-logo-app

    So B is most acidic not C
