NEETChemistryAldehydes Ketones and Carboxylic AcidsMCQ+4 / −1
The correct order of strengths of the carboxylic acids
is
is
- AI > II > III
- BII > III > I
- CIII > II > I
- DII > I > III
View written solutionFree
Correct answer: B
We know, Acidic strength – I effect
As oxygen is more electron withdrawing (II) and
(III) show greater – I effect than (I). Thus, (I) is least
acidic. Out of (II) and (III), (II) is more acidic than
(III) as distance of O increases from —COOH group
and acidic strength decreases.
