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.

+M effect of OH greater than OCH3 Explanation:- The -R group in -OR causes steric repultions with lone pairs, increasing bond angles. Due to which %s character is increased; making -O- atom of -OR more electro-negative and thus affecting donor tendency.
didn't get
lone pair ke sath repulsions hone se bond angle badhta hai...and bond angle directly proportional to percentage s character which is directly proportional to electronegativity...so donor tendency kam ho jayenge
sir but mane to + r poocha tha
maine bhi yhi likha h
