In molecular orbital theory, which of the following orbitals is the highest energy in O2?

Step 1: Understand that O2 is a molecule made of two oxygen atoms.
Step 2: Learn about molecular orbitals, which are formed when atomic orbitals combine.
Step 3: Know that in O2, the atomic orbitals from each oxygen atom combine to form molecular orbitals.
Step 4: Identify the types of molecular orbitals formed: sigma (σ) and pi (π) orbitals.
Step 5: Recognize that the 2p orbitals can form π2p orbitals in O2.
Step 6: Compare the energy levels of the molecular orbitals: σ2p, π2p, and others.
Step 7: Conclude that the π2p orbitals are higher in energy than the σ2p orbitals in O2.

Molecular Orbital Theory – A theory that describes the electronic structure of molecules using molecular orbitals, which are formed from the combination of atomic orbitals.
Orbital Energy Levels – In molecular orbital theory, different orbitals have distinct energy levels, and the arrangement of electrons in these orbitals determines the stability and properties of the molecule.
Oxygen Molecular Orbitals – In O2, the molecular orbitals are filled according to their energy levels, with π2p orbitals being higher in energy than σ2p orbitals.
