Ethanol, sometimes called methylated spirits, ethyl alcohol, or just alcohol, is a member of a group of organic chemicals called alcohols. Ethanol has the chemical formula of CH₃CH₂OH, with the OH (hydroxyl ion) being the functional group. Because of the presence of the -O H hydrogen bonding is quite common. Due to the fact that the hydroxyl group is attached to a carbon atom which is itself attached to only one other carbon atom, ethanol is referred to as a primary alcohol. Ethanol is a colorless liquid with a boiling point of 172°F (78°C), and a characteristic sweet smell. Ethanol can be found in nature as a natural product of the fermentation of carbohydrates such as starch and, most commonly, sugar by certain yeasts, bacteria, and molds. For human consumption, ethanol is still manufactured by fermentation. Industrially ethanol is now mostly frequently manufactured by...
