Question

What are single bonds?

Answer 1

A bond involving only two valence electrons...

Explanation:

A single bond is a bond in which two atoms share two valence electrons each, forming a covalent bond. It is written usually as `A-A` or `A:A` in Lewis structures. All single bonds are linear. Examples of single bonds include `C-H,H-H,H-F`, and many more, usually involving hydrogen atoms.

Usually, single bonds are sigma bonds, where atomic orbitals overlap each other head-on.
