1. A Review of General Chemistry

Draw orbital pictures of the pi bonding in the following compounds:

a. CH₃COCH₃

b. HCN

Indicate the kind of molecular orbital (σ, σ*, π, or π*) that results when the two atomic orbitals are combined:

a. <IMAGE>

b. <IMAGE>

Draw the following orbitals:

a. 3s orbital

b. 4s orbital

c. 3p orbital

A molecular orbital diagram is shown for the C―Cl bond in chloromethane. If two more electrons were added to chloromethane, where would the electrons go?

Which type of molecular orbital is typically represented by a boundary-surface diagram showing two lobes with a nodal plane between them along the internuclear axis?
