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.

isme nitrogen ke lone pair se imminium ion pe direct attack kyu nhi ho skta
Pyrrole N lone pair is involved in resonance na
resonance to double bond bhi krega na?
see double bond jab attack karega to intermediate stable banega by resonance.

nitrogen se attack karwa ke dekho aisa koi resonance nahi hoga
ok got it more resonance ki bjh se db se attack hoge
