Question

What is a sigma (σ) bond?
Options
A A covalent bond formed when two orbitals overlap sideways
B A single covalent bond formed when two orbitals overlap end-to-end, with electrons found between the two nuclei
Correct Answer
C A bond formed by the transfer of electrons
D A weak intermolecular attraction
Correct Answer

Option B is the correct answer.

Detailed Explanation

A sigma (σ) bond is a single covalent bond formed when two atomic orbitals overlap end-to-end along the internuclear axis. The shared electron pair is located between the two nuclei, providing strong bonding.

Hint

Sigma bonds have electron density concentrated along the axis between nuclei.
