Question
16. In valence bond theory, the pi bond between the two carbon atoms in C2H4 results from: (1) the overlap of the 2s orbitals from each carbon atom. (2) the overlap of a 2s orbital from one carbon atom with a 2p orbital from the other carbon atom (3) the above and below the molecular plane overlap of a 2p orbital from each carbon atom. (4) the above and below the molecular plane overlap of a 2s orbital from one carbon atom a 2p orbital from the other carbon atom. (5) the end to end overlap of a 2p orbital front each carbon atom.
