Question
Which of the following statements is true regarding the 𝜋𝜋 molecular orbitals of benzene?Select answer from the options belowAll six MO's are antibonding.There are four bonding MO's and two antibonding MOs.There are three bonding MO's and three antibonding MO's.All six MO's are bonding.
Solution
The correct statement regarding the 𝜋𝜋 molecular orbitals of benzene is: "There are three bonding MO's and three antibonding MO's."
Here's why:
Benzene is a cyclic compound with a ring of six carbon atoms. Each carbon atom contributes one 2p electron into the π system. These six electrons occupy three molecular orbitals (MOs) that are lower in energy than the isolated p atomic orbitals, so these are bonding MOs. The other three MOs are higher in energy than the isolated p atomic orbitals, so these are antibonding MOs. Therefore, there are three bonding MO's and three antibonding MO's in the 𝜋 system of benzene.
