Single, Double, and Triple Bonds: Understanding Bonding Pairs

Single Bonds: Sharing One Pair of Electrons

Definition

Single bond

A single bond occurs when two atoms share one pair of electrons.

This is the simplest type of covalent bond.
A single line (—) represents a single bond in a Lewis structure.

Example

The hydrogen molecule (H₂) forms when two hydrogen atoms each contribute one electron to share a pair.
This shared pair creates a single bond: $H:H$ or $H—H$

Double Bonds: Sharing Two Pairs of Electrons

Definition

Double bond

A double bond forms when two atoms share two pairs of electrons.

This type of bond is stronger and shorter than a single bond.
A double line (=) represents a double bond in a Lewis structure.

Example

In an oxygen molecule (O₂), each oxygen atom shares two electrons with the other, forming a double bond: $O::O$ or $O=O$
