Question

The correct order of increasing acid strength of the compounds :
(A)$CH_{2} CO_{2} H$
(B) $MeOCH_{2}CO_{2}H$
(C) $CF_{3} CO_{2}H$
(D)

• A. $B<\, D<\, A<\, C$
• B. $B<\, A<\, C<\,B$
• C. $B<\, A<\, B<\,C$
• D. $A<\, D<\, C<\,B$

Answer 1

Answer: (C)

-I effect increases acidity. +I effect decreases acidity. -$CF_{3}$ exerting more -I effect than MeO - $Me_{2}$CH- exerting more +I effect than —$CH_{3}$
