CD4 Carbon Chemistry Allotropes of carbon Allotropes are different forms of the same element in the same state. Carbon has 3 allotropes : diamond , graphite and buckminster fullerene. Diamond Graphite Buckminster Fullerene Properties and Uses Diamond: Is extremely hard and can be used as jewelry or in cutting tools.It does not conduct electricity. Graphite: Is soft and can be used as a lubricant. It conducts electricity. Hydrocarbons Any compound which is made up only of the elements hydrogen and carbon is called a hydrocarbon. Alkanes are a series of saturated hydrocarbons. This means that they are held together with single bonds only. Alkenes are a series of unsaturated hydrocarbons. This means that their molecules contain 1 carbon to carbon double bond (C=C). Testing for Alkenes: If you add bromine water (which is red/brown coloured) to an alkene then they react and the mixture turns colourless. Alkanes and alkenes are both useful as fuels. Refining Crude Oil Oil is made up of many...
