A description of bonding in
a. Construct diagrams similar to Figure 11-33 to indicate the overlap of the three atomic orbitals in forming the three molecular orbitals. Assume that the order of energy of the molecular orbitals is bonding MO< nonbonding MO < antibonding MO.
b. Sketch a molecular orbital energy-level diagram, and assign the appropriate number of electrons from fluorine and xenon to the molecular orbitals. What is the bond order?
c. With the aid of VSEPR theory, show that this molecular orbital description based on three-center bonds works well for

- In the molecular orbital mode l, compare and contrast bonds with bonds. What orbitals form the bonds and what orbitals form the bonds? Assume the z-axis is the internuclear axis.arrow_forwardCompare and contrast the molecular orbital and ionic bonding descriptions of LiF.arrow_forwardThe structure of amphetamine, a stimulant, is shown below. (Replacing one H atom on the NH2, or amino, group with CH3 gives methamphetamine a particularly dangerous drug commonly known as speed.) (a) What are the hybrid orbitals used by the C atoms of the C6 ring. by the C atoms of the side chain, and by the N atom? (b) Give approximate values for the bond angles A, B, and C. (c) How many bonds and bonds are in the molerule? (d) Is the molecule polar or nonpolar? (e) Amphetamine reacts readily with a proton (H+) in aqueous solution. Where does this proton attach to the molecule? Explain how the electrostatic potential map predicts this site of protonation.arrow_forward
