Question

The correct order of increasing acid strength of compounds:

• A. B < D < A < C
• B. D < A < C < B
• C. D < A < B < C
• D. A < D < C < B

Answer 1

The correct option is C D < A < B < C

$C{H}_3$ is a +I and thus compounds (a) and (d) have lesser acidic strength.
Out of (a) and (d), (d) is less acidic because it has two methyl group.
$C{F}_3$ is strong EWG and therefore (c) has the highest acidic strength out of the four compounds.
$MeO$ is weak EWG.
