Answer

Explanation:

Step1: Identify the MO symbol

The molecular orbital is formed by side - on overlap of 3p orbitals, which gives a $\pi$ orbital. Since there is no indication of antibonding (no node between the nuclei), it is a $\pi$ bonding orbital, symbol is $\pi$.

Step2: Determine bonding or antibonding

The orbital has electron density between the nuclei. In a bonding molecular orbital, electron density is concentrated between the nuclei, so it is a bonding MO.

Step3: Compare energy

Bonding molecular orbitals have lower energy than the atomic orbitals from which they are formed. So the energy of this $\pi$ bonding MO is lower 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? bonding What is the energy of this MO, compared to the energy of a 3p orbital on one of the separate atoms? lower
