Answer

Explanation:

Step1: Identify the molecular - orbital type

When two 3p atomic orbitals combine side - on, they form a $\pi$ molecular orbital. The sketch shows a side - on combination, so the symbol is $\pi$.

Step2: Determine bonding or antibonding

The lobes of the same phase are not overlapping constructively between the nuclei. In an antibonding orbital, there is a node between the nuclei. So, this is an antibonding MO.

Step3: Compare energy

Antibonding molecular orbitals have higher energy than the atomic orbitals from which they are formed. So, the energy of this MO is higher than the energy of a 3p orbital on one of the separate atoms.

Answer:

Write the symbol for this MO: $\pi$ Is this a bonding or antibonding MO? antibonding What is the energy of this MO, compared to the energy of a 3p orbital on one of the separate atoms? higher
