• The amount of carbon in the earth’s crust is merely 0.02%, which is available in the form of minerals such as carbonates, hydrogen-carbonates, coal, and petroleum.
• The presence of carbon in the atmosphere of the earth is 0.03%, in the form of carbon dioxide.
• The compounds of carbon and hydrogen is called hydrocarbon.
• The hydrocarbon are of two types, saturated and unsaturated.
• The saturated hydrocarbon has single bond between carbon-carbon atoms.
• The unsaturated hydrocarbon has double or triple bound between carbon-carbon atoms.
• The group of compound which determines the property of hydrocarbons is called functional groups.
