a type of chemical bond between two atoms involving the sharing of two pairs of electrons, resulting in a stronger and more stable connection than a single bond
Exemplo
Unsaturated fats have double bonds between carbon atoms in their hydrocarbon chains, contributing to their liquid state at room temperature.
In organic chemistry, molecules like formaldehyde (CH₂O) contain double bonds between carbon and oxygen atoms.
Double bonds are essential in the formation of aromatic compounds like benzene, which contains alternating single and double bonds between carbon atoms.
The double bond in oxygen gas (O₂) consists of two pairs of shared electrons, making it a stable diatomic molecule.
Ethylene (C₂H₄) contains a double bond between two carbon atoms, allowing it to participate in polymerization reactions.
