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.

Acidity order 4>3>2>1 Explanation:- At para position methyl group show hyperconjugation effect (+H) which decreases the acidity of phenol. In case of para tert butyl phenol there is no hyperconjugative effect as no alpha hydrogen and +H effect increases from 4 to 1 so acidity decreases in the order. Hence acidity order will be 4>3>2>1
got this?
Sir how can we decide which compound will have resonance,inductive or hyperconjugative effect?
yes i got this...
first read the concept of all electronic effect and then order of these effect and after practicing questions you can get this concept
