The formaldehyde molecule has a ? bond between the carbon and oxygen atom. Which of the following statements about this bond is not true? A) This bond has two overlap sites that occur above and below the C-O axis. B)The figure-8 bond orbitals around the carbon and oxygen atoms actually extend to infinity but do have two overlapping areas. C)This bond is the result of the interaction of an unpaired carbon electron in the 2s orbital and an unpaired oxygen electron in the 2p orbital. D)Because carbon has four valence electrons and three of them were assigned lone electron sites in the three hybrid orbitals, there is one 2p orbital left in the carbon atom that participates in this ? bond
