Dear teachers,
I have been arguing with my teacher that Carbon forms triple bond with Oxygen , leaving 2 lone pairs, one at Carbon and one at Oxygen but she still insists that they would not form triple bond but double bond. She asserted that dative bond ( as oxygen contributes 4 electron in the triple bond) would not exist together with shared pairs of electrons in the same bond.Frankly speaking, I do not understand what she has said and I still believe my point of view.
I would be grateful if you can clarify my doubts by describing and drawing the lewis structure of CO.
Thanks in advance!
