∙ Ethanol has antibacterial properties as it helps to kill many bacteria, viruses, and fungi (by denaturing their proteins and dissolving their lipids). It is thus used in medical/antibacterial wipes and in hand sanitizers.
∙ Ethanoic or acetic acid is used in making dyes, pigments, and paint and coating additives.
∙ Ethane is used in the production of ethylene for making plastics, anti-freeze and detergents; it's a ripening agent for foods, a refrigerant.
∙ Methane is used primarily as fuel to make heat and light. It is also used to manufacture chemicals.
