Ethane, C2H6, has a boiling point of -89°C at standard pressure. Ethanol, C2HsOH, has a much higher boiling point than ethane at standard pressure. At STP. ethane is a gas and ethanol is a liquid.

59 Identify the class of organic compounds to which ethanol belongs.

60 A liquid boils when the vapor pressure of the liquid equals the atmospheric pressure on the surface of the liquid. Based on Table H, what is the boiling point of ethanol at standard pressure?

61 Compare the intermolecular forces of the two substances at STP. [1]
