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
