| Introduction |
|
| Man's quest for sources of energy is
inexhaustible. Early man depended mainly on muscular energy and later began to use wind and flowing water as sources of energy. He learned the art of making and controlling fire. Fire became his source of light at night. He used fire for warmth and realized that cooked food tastes better than raw food. As civilization advanced, man started using fire in making weapons, pottery etc. Today, with the progress in science and technology, fuels have become indispensable to man. |

| There is no other element that touches our life as much as carbon does. Proteins, fats, sugars, oils etc., are vital for life. Dyes, drugs, cosmetics, detergents, fibres, paper and fuels have become an inevitable part of our life. All these contain carbon. |
| |
| The chemistry of carbon and its compounds prevades almost every aspect of our lives. It is hard to imagine life and civilization without carbon and its compounds. |
