Question #4 & #5?

3) Using Early and Late Molecular Orbitals, draw the two M.O. diagrams for NO , determine which is most stable; calculate and state bond order of each, state diamagnetic or paramagnetioc d if paramagnetic and by how many electrons. an 4) If four hydrogens, each with its 1s orbital, and two carbons, each with its one 2s and three 2p orbitals, form a molecule, then how many molecular orbitals will there be? How many bonding orbitals, and how many antibonding orbitals? 5) If four hydrogens, each with its 1s orbital, and one carbon, with its one 2s and three 2p orbitals, form a molecule, then how many molecular orbitals will there be? How many bonding orbitals, and how many antibonding orbitals? 6) Draw a picture of the types bonds and antibonds for the overlapping of two p-orbitals. 7) Draw a picture of the types bonds and antibonds for the overlapping of two s-orbitals. 8) If sodium atoms form a ABC closest packing arrangement of atoms in the solid phase, then how many sodium atoms are in contact with any one sodium atom (coordination number), how many valance orbitals can be used to bond for each atom, how many total atomic orbitals can be used hy this sodium atom and all the attached sodium atoms, how many molecular orbitals will

Answer 1

Since there are four Hydrogen and two carbon atom, so they will from ethane molecules and This can be explain by MOT CH_2 = CH_2 Total number of electron = 12 Number MOS = 8 Number of bonding molecular orbitals = 4 Number of anti-bonding MOS = 4 since 1 carbon atom and 4 hydrogen atom result in formation of CH_4 Total no. of MOS = 8 Bonding MOS = 4 Antibody MOS = 4 Total e^- s = 8
