Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Molecular Orbitals (MOs)

Molecular orbitals are formed by the linear combination of atomic orbitals (LCAO) when atoms bond together. They can be classified as bonding, antibonding, or non-bonding, depending on the phase relationship of the combining atomic orbitals. The shape and energy of these orbitals determine the stability and reactivity of the molecule.

Atomic Orbitals

Atomic orbitals are regions in an atom where there is a high probability of finding electrons. They are categorized into different types, such as s (spherical) and p (dumbbell-shaped), each with distinct shapes and orientations. The combination of these orbitals during molecular formation leads to the creation of molecular orbitals.

Contour Representation

Contour representation visually depicts the regions of positive and negative phase in molecular orbitals. The positive regions indicate where the probability of finding electrons is high, while the negative regions show areas of destructive interference. This representation helps in understanding the bonding characteristics and electron distribution within the molecule.
