Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

1>2>3 Explanation- The decreasing order of the relative acidic strengths of o-toluic , m- toluic acid and p-toluic acid is: o-toluic acid > m-toluic 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 m-toluic acid. The ortho-isomer of every substituted benzoic acid is the strongest acid due to ortho effect. https://youtu.be/mCavm85yzR8
