The correct order of increasing acid strength of the compounds
(A) $\mathrm{CH}_{3} \mathrm{CO}_{2} \mathrm{H}$
(B) $\mathrm{MeOCH}_{2} \mathrm{CO}_{2} \mathrm{H}$
(C) $\mathrm{CF}_{3} \mathrm{CO}_{2} \mathrm{H}$
(D)


is
  1. $D < A < B < C$
  2. $A < D < B < C$
  3. $B < D < A < C$
  4. $D < A < C < B$

Solution

The correct order of increasing acid strength $(\mathrm{Me})_{2} \mathrm{CH} . \mathrm{COOH} < \mathrm{CH}_{3} \mathrm{COOH} < \mathrm{MeOCH}_{2} \mathrm{COOH}$ $ < \mathrm{CF}_{3} \mathrm{COOH}$
Electron withdrawing groups increase the acid strength and electron donating groups decrease the acid strength. ^
