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.

option D is correct
where you have doubt?
why a is less acidic than b and d
B and D jyada Resonance stabised carbanion hai..
cross conjugation hai B and D me...
got?
yes sir
👍
sir but extended conjugation is more stability than cross
carbanion ki stability check karo shweta...B and D me two C=O ke sath resonance me hai but A me only 1 C=O ke sath
ok sir
got it
sir ik doubt hai cross conjugation main to 3 double bond hote hai
haa usme middle one dono side wale ke sath conjugation me hote hai...or jo side wale hote hai wo conjugation me nhi hote hai
negative charge ke sath bhi same case ho sakte hai
okokok
thanku
