Structural Formula of Ethene (C2H4): CH2=CH2
Explanation of Physical Properties:
- Boiling Point: Ethene has a lower boiling point than ethane. This is because the intermolecular forces between ethene molecules (London Dispersion Forces) are weaker than the intermolecular forces between ethane molecules. Ethane molecules are larger and have more electrons, resulting in stronger London Dispersion Forces.
- State at Room Temperature: Ethene is a gas at room temperature, while ethane is a gas at room temperature. This is due to the difference in boiling points.
- Solubility: Ethene is less soluble in water than ethane. This is because ethene is non-polar and ethane is slightly more polar due to the difference in electronegativity between carbon and hydrogen. Water is a polar solvent and dissolves polar substances more readily.
