Contains at least one C=C or C≡C bond.
Sigma Bond Definition
A covalent bond formed by the linear overlap of atomic orbitals.
Pi Bond Definition
A covalent bond formed by the sideways overlap of p orbitals.
Bond Length Definition
The distance between the nuclei of two covalently bonded atoms.
Hydrogenation Definition
Addition of a hydrogen molecule across a C=C bond.
