In the molecular orbital theory, which of the following pairs of orbitals can combine to form a sigma bond?

In the molecular orbital theory, which of the following pairs of orbitals can combine to form a sigma bond?

Correct Answer: s and s orbitals

Step 1: Understand what a sigma bond is. A sigma bond is a type of covalent bond that is formed when two atomic orbitals overlap directly along the axis connecting the two nuclei.
Step 2: Identify the types of orbitals that can combine to form a sigma bond. The common pairs that can form a sigma bond include s and s orbitals, s and p orbitals, and p and p orbitals.
Step 3: Focus on the specific pair mentioned in the question, which is s and s orbitals.
Step 4: Recognize that when two s orbitals from different atoms come together, they can overlap and form a sigma bond.

Molecular Orbital Theory – A theory that describes the electronic structure of molecules using quantum mechanics, focusing on the combination of atomic orbitals to form molecular orbitals.
Sigma Bonds – A type of covalent bond formed by the head-on overlap of atomic orbitals, allowing for electron density along the bond axis.
Orbital Combinations – Understanding which types of atomic orbitals (s, p, d, etc.) can combine to form different types of bonds, including sigma and pi bonds.
