Here's a breakdown:
* Covalent bond: A chemical bond formed by the sharing of electron pairs between atoms.
* Double bond: Two pairs of electrons are shared between two atoms.
Examples:
* Oxygen (O2): Each oxygen atom shares two electrons with the other oxygen atom, forming a double bond.
* Carbon dioxide (CO2): Each carbon atom forms a double bond with each oxygen atom.
Key features of double bonds:
* Stronger than single bonds: Due to the sharing of more electrons, double bonds are stronger and shorter than single bonds.
* Planar geometry: The atoms involved in a double bond and the atoms directly attached to them usually lie in the same plane.
* Restricted rotation: Rotation around a double bond is restricted, leading to the existence of isomers (molecules with the same chemical formula but different arrangements of atoms).
