Ma'am one confusion , is there any sigma d plane bcz the 3 sigma v plane bisect the two C2 axes...so I think there is three sigma d plane...
there are 3 vertical planes (sigma v) and no sigma d coz for sigma d the plane should bisect both angles between 2 C2 axes. That plane only bisect one angle 120 degree and the other side cutting through the B-F bond
why does C3 work when the double bond is no longer in the same place. Is it because of resonance?
Explanation was very good😇
Thank you. Hope it helps you
