The relative acidic strengths of benzoic acid, o-toluic acid, and p-toluic acid in decreasing order can be given as:
Open in App
Solution
The correct option is D o-toluic acid > benzoic acid > p-toluic acid
The decreasing order of the relative acidic strengths of benzoic acid, o-toluic acid and p-toluic acid is:o-toluic acid > benzoic acid > p-toluic acid.
In a case of p-toluic acid, a methyl group is an electron releasing substituent and intensifies the negative charge of the carboxylate anion and destabilizes it and decreases the acidity. Hence, p-toluic acid is less acidic than benzoic acid.
The ortho-isomer of every substituted benzoic acid is the strongest acid due to ortho effect.
