Question

A sigma (σ) bond is formed by the:
Options
A side-by-side overlap of p-orbitals
B end-to-end overlap of atomic orbitals
Correct Answer
C overlap of d-orbitals only
D interaction of a full orbital with an empty one
Correct Answer

Option B is the correct answer.

Detailed Explanation

A sigma bond is characterized by the direct, end-to-end overlap of atomic orbitals (s-s, s-p, or p-p) along the internuclear axis, resulting in electron density concentrated between the nuclei.

Hint

This bond type is the strongest and is formed first between two atoms.
