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.

When any group is present at ortho to carboxyl group in substituted benzoic acid then the acidic character of that compound becomes at least more than benzoic acid.

This is due to ortho effect which is observe only in the case of benzoic acid(SIR effect) and aniline(SIP effect)
so that means it will be just more acidic than normal benzoic acid -m ,-I containing grp will be highly acidic that Ortho substituted??
Any grp at ortho position increases acidity of benzoic acid
Example- both ortho methyl benzoic acid and ortho nitro benzoic acid is more acidic than benzoic acid....but if we compare ortho methyl benzoic acid and ortho nitro benzoic acid...then later is more acidic
