Organic Chemistry
Which of the following is not correct?
Between two similar or dissimilar atoms, only one sigma bond is possible whereas two pi bonds can be formed between them. Explain.
Only one sigma bond is possible and two pi bond is because after forming side on side in equitorial direction, remaining bond can be formed in $${ 90 }^{ 0 }$$ to the actual bond i.e. end on end overlap takes place.
