Concept explainers
(a)
Interpretation:
The MO resulting from the given orbital interaction is to be drawn.
Concept introduction:
When atomic orbitals (AOs) of the opposite phases interact, they result in an antibonding molecular orbital (MO) that is higher in energy than the individual AOs.
(b)
Interpretation:
Whether the resulting MO is unique compared to the one shown on the right of Figure 3-6b is to be determined.
Concept introduction:
When atomic orbitals (AOs) of opposite phases interact, the resulting molecular orbital (MO) has higher energy than the separate AOs. Whether the phases of the two are negative and positive as shown here or positive and negative, the result is an MO that is raised in energy to the same extent.
