A sigma bond forms:

1. when two orbitals directly overlap but there is only one bonding interaction.
2. when two orbitals directly overlap and there are two bonding interaction.
3. when two valence electrons combine into one orbital.
4. when two atoms overlap and the valence electrons bond E. the creation of an S shaped orbital.

Correct answer: when two orbitals directly overlap but there is only one bonding interaction.

Solution

A sigma bond is formed by end-to-end overlap of two orbitals along the line joining the nuclei, creating one bonding interaction. This is the first and strongest bond between two atoms, unlike pi bonds which involve side-by-side overlap.
