What is an alkene and its general formula? It is an unsaturated hydrocarbon with a least one C=C bond. General formula is CnH2n What is a sigma bond? σ single covalent bond formed when two s orbitals overlap. High electron density What is a pi bond? sideways overlap of p orbitals that occur in a double or triple bond. Much weaker than sigma, low bond enthalpy and lower electrostatic attraction Is an alkane or an alkene more reactive? Alkene. contains both sigma and pi bonds with high ele...
