The correct order of the strengths of the carboxylic acids
is
I > II > III
II > III > I
III > II > I
II > I > III
As we learnt in
Acidic strength of carboxylic acid -
– More acidic than phenols or alcohols.
– Acidity increase with the presence of a group with -I effect in the alkyl group.Whereas it decreases with the presence of +I group.
– Acidity increases with increase in the number of halogen atoms on - position.
– It decreases with increasing distance of halogen from
– It increases with increase in the electronegativity of halogen.
-
Negative inductive effect increases acidity of carboxylic acid.
