A carbon-carbon double bond is a type of covalent bond formed between two carbon atoms, consisting of two shared pairs of electrons. It commonly exists between two adjacent carbon atoms in organic molecules and is represented by the chemical symbol C=C. The double bond is formed by the overlap of two hybrid orbitals, one sp2 orbital from each carbon atom. The sp2 hybridization results in a trigonal planar molecular geometry around each carbon atom, with the double bond oriented in the same plane as the other three bonds. The carbon-carbon double bond is a strong bond with a bond length of about 1.34 Å, which is shorter than a carbon-carbon single bond. It is a reactive functional group that undergoes a wide variety of chemical reactions.
