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.

meta chlorobenzoic acid> para chloro benzoic acid> benzoic acid> para toluic acid As we know that Acidity is directly proportional to EWG and inversily proportional to ERG. CH3 group at Para position show +H effect so it decrease the stability of benzoic acid in greater extent. so I is least acidic while Cl at o,ma and p position show -I effect and increase the acidity of benzoic acid so II and III have more acidiy. out of these III is more basic than II because of less distance make benzoic more acidic. so overall III>II>IV>I
in case of any doubt please ask me.
