What is a double bond in chemical terms?

A double bond in chemical terms refers to a situation where two pairs of electrons are shared between two atoms. This bonding occurs when two atoms each contribute two electrons, resulting in a stronger bond compared to a single bond, where only one pair of electrons is shared.

Double bonds are commonly found in various organic compounds, such as alkenes, and are crucial in defining the chemical properties and reactivity of these compounds. For example, the presence of a double bond can affect the geometry of the molecule, impacting how it interacts with other molecules and facilitates reactions. Understanding double bonds is essential in the study of chemistry, especially in organic and biochemical contexts, as they play a significant role in determining the characteristics of many substances in the natural world.
