WebThe alkenes have the general formula \ ( {C_n} {H_ {2n}}\). The alkenes are unsaturated. This means that they have a carbon to carbon double bond. The alkanes are saturated because they only contain single bonds. An unsaturated hydrocarbon decolourises bromine water quickly. Alkanes do this slowly. Alkenes can be used as fuels, solvents and ... WebYou can calculate the energy change in a reaction using average bond energies. Bond energy is the amount of energy needed to break one mole of a particular bond. To calculate bond energy...
