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 A is aromatic
sir can you explain why not b
Dear shib if it is singlet carbene then it is aromatic...if it is lone pair then it is antiaromatic
sir if it is carbene i read that carbene lp do not participate in resonance as bcz lp is present perpendicular to the other adjacent p orbitals but carbene having vacant orbital so that vacant orbital can participate in resonance
yes here special type of conjugation occurs...so if carbene then 2nd one is aromatic
