Distinguish between ethane and ethylene in two ways?

1. Chemical structure: Ethane is a saturated hydrocarbon with the chemical formula C2H6, consisting of two carbon atoms bonded to each other with single bonds and each carbon atom bonded to three hydrogen atoms. Ethylene, on the other hand, is an unsaturated hydrocarbon with the chemical formula C2H4, consisting of two carbon atoms bonded to each other with a double bond and each carbon atom bonded to two hydrogen atoms.

2. Physical properties: Ethane is a colorless, odorless gas at room temperature and pressure, while ethylene is a colorless gas with a slightly sweet odor. Ethane is relatively inert and non-reactive, while ethylene is a highly reactive compound that is used in various industrial processes such as the production of plastics and chemicals.

1. Structure: Ethane is an alkane, meaning it has a carbon-carbon single bond, while ethylene is an alkene, meaning it has a carbon-carbon double bond.

2. Physical properties: Ethane is a gas at room temperature, while ethylene is a liquid. This is because ethane has weaker intermolecular forces than ethylene.
