Question

Which of the following is the strongest acid: (A) formic acid (B) acetic acid (C) trichloroacetic acid (D) trifluoroacefic acid

Tardigrade Admin · Accepted Answer

Due to the strongest -I effect of F-atom C F3 C O O H is strongest acid than rest other acids. Decreasing order of acidity CF 3 COOH > CCl 3 COOH > CH 3 COOH > HCOOH

Q. Which of the following is the strongest acid:

formic acid

acetic acid

trichloroacetic acid

trifluoroacefic acid

Due to the strongest $- I$ effect of $F$ -atom $C F_{3} COO H$ is strongest acid than rest other acids. Decreasing order of acidity
$C F_{3} COO H > CC l_{3} COO H > C H_{3} COO H > H COO H$

Due to the strongest −I effect of F-atom CF3​COOH is strongest acid than rest other acids. Decreasing order of acidity CF3​COOH>CCl3​COOH>CH3​COOH>HCOOH

Due to the strongest $- I$ effect of $F$ -atom $C F_{3} COO H$ is strongest acid than rest other acids. Decreasing order of acidity
$C F_{3} COO H > CC l_{3} COO H > C H_{3} COO H > H COO H$
