Chemistry C7

Alkanes

• Alkanes are chains of carbon atoms surrounded by hydrogen atoms
• Alkanes only contain ONE covalent bond
• Examples of Alkanes include Methane, Ethane, Propane and Butane
• Alkanes burn to give Carbon Dioxide and Water

Alkane+Oxygen -> Carbon Dioxide + Water

• Alkanes are almost completely unreactive because of their C-C and C-H bonds

Alcohols

• Alcohols always have an -OH group
• Alcohols are soluble in water
• Alcohols have a lower boiling point thanwater and alkanes
• Alcohols evaporates easily, releasing fumes which are highly flammable
