Inorganic chemistry

1. Draw the following representations of 1s sigma bonding and sigma antibonding orbitals in H₂:

 

1. as a combination of radial wavefunctions

 

1. as a contour map

 

sigma bonding                                             sigma antibonding

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Draw an energy level diagram showing how two 1s orbitals on different hydrogen atoms come together to form the bonding and antibonding orbitals.

 

 

 

 

 

 

 

 

 

2. a. Draw an energy level diagram for the superoxide anion, O₂^–. Do you expect this ion to have an O-O bond length that is shorter than or longer than O₂^–? Why?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Draw a contour map of the orbital in which the highest energy electron exists.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. a. Do you expect O₂⁺ to have a longer or shorter bond than O₂? Why?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Can you think think of a reason why can O₂^– be observed in some situations in biochemistry and inorganic chemistry, but O₂⁺ is only observed under rare conditions?
