(This is a question from MS Chouhan. I posted this question many times but I not get any satisfactory answer.This is a question of pi electrons but I have a doubt .Oxygen is sp2 hybridised which means it has only 1 p orbital so only 1 electron pair is considered as a pi electron but in answer both lone pairs are considered.Can you please clear my doubt. What is the relation between lone pair and pi electrons. Why both lone pairs are considered as pi electron as oxygen have only one p orbital) Q-How many pi electrons are present in the following compound? Ans-10(This ia from MS Chouhan so answer must be correct.)
