The correct order of the acidity of following acids is-
CH3COOH, HCOOH, Cl-CH2COOH, F-CH2COOH, (Cl2)CHCOOH
Cl2CHCOOH > F-CH2COOH > Cl-CH2COOH > HCOOH > CH3COOH
F-CH2COOH > Cl-CH2COOH > Cl2CHCOOH > HCOOH > CH3COOH
HCOOH > CH3COOH > Cl-CH2COOH > Cl2CHCOOH > F-CH2COOH
None of the above
A.
Cl2CHCOOH > F-CH2COOH > Cl-CH2COOH > HCOOH > CH3COOH
Group or atom attached with -COOH group shows positive inductive effect increases electron density on oxygen atom, which suppress the ionisation of H+, hence, acidic strength decreases.
Group or atom attached with -COOH group shows negative inductive effect decreases electron density on oxygen atom, which facilitate the ionisation of H+, hence acidic strength increases.
Sequence of group shows negative inductive effect-
-CHCl2 > -CH2F > -CH2Cl
-CH3 group shows positive inductive effect and -H does not show any effect.
Therefore, the correct order is-
Cl2CHCOOH > F-CH2COOH > Cl-CH2COOH > HCOOH > CH3COOH
