INTRODUCTION TO ORGANIC CHEMISTRY
THE COMPOUNDS OF HYDROGEN AND CARBON ARE CALLED AS HYDROCARBONS.THE CHEMISTRY WHICH DEALS WITH HYDROCARBONS AND THERE DERIVATIVES IS KNOWN AS ORGANIC CHEMISTRY.THE FIRST ORGANIC COMPOUND TO MADE IN LABORATORY WAS ACETIC ACID BY KOLBE. AND THE FIRST ORGANIC COMPOUND TO SYNTHESISED WAS UREA BY WOHLER. ''TODAY A LARGE NUMBER OF ORGANIC COMPOUNDS ARE SYNTHESISED ,ABOUT 90% OF OUR KNOWN COMPOUNDS ARE ORGANIC COMPOUNDS,ORGANIC COMPOUNDS HAVE UNIQUE PROPERTIES LIKE ISOMERISM AND CATENATION. MAXIMUM OF INORGANIC COMPOUNDS ARE FORMED BY IONIC COMPOUNDS,WHERE AS ORGANIC COMPOUNDS SHOWS UNIQUE PROPERTY OF MAKING COVALENT BONDS,''

SOURCES OF ORGANIC COMPOUNDS-
PLANTS,ANIMALS,FUNGI AND MICRO ORGANISM ,COAL. CATENATION -''THE PROPERTY OF SELF LINKAGE IS KNOWN CATENATION. IT DEPENDS UPON THE VALUE OF BOND ENERGY,WHICH IS MAXIMUM IN CASE OF CARBON.THE STABILITY AND TENDENCY TO MAKE BOND DECREASES AS THE BOND ENERGY DECREASES.HENCE,THE TENDENCY OF CATENATION DECREASES .THE TENDENCY OF CATENATIN DECREASES IN THE FOLLOWING MANNER'' C>SI>S>P>N>O

IMPORTANCE OF ORGANIC COMPOUNDS
organic compounds play an important place in our lives.The following list clearly illustrates imoprtance of organic compounds. 1 Food- carbohydrates,fats, protiens ,vitamins. 2 Clothes- cotton,silk,nylon,dacron. 3 Fuel-coal,wood,natural gas, petrol . 4 Medicines- Penicillin,cocaine,chloromycetin,morphine. 5 Explosives-Nitroglycerine,Nitrocellulose,T.n.b,T.n.t . 6 Dyes- Malachite green, indigo,alizarin .
