PCl4+ SF4 WRONG According to molecular orbital (MO) theory, the twelve valence electrons in the O2 molecule are distributed as follows:ġ0 in bonding MOs, 2 in antibonding MOs. In which of the following species does the central atom violate the octet rule? are free to move around the six-membered ring. Give rise to alternating single and double bonds around the ring. The electrons in the delocalized molecular orbitals of benzene (C6H6)Īre confined between two adjacent bonding atoms.Īre free to move around the six-membered ring.Īre unevenly distributed through the molecule.įorm the electron pairs in the C-H bonds of the compound.
