Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at first‚ then in Germany‚ later on in England. By far the largest variety of materials that bombard us are made up of organic elements. The beginning of the Ninetieth century was also the dawn of chemistry‚ all organic substances were understood as all being materials

Four elements‚ hydrogen‚ carbon‚ oxygen and nitrogen‚ are the major components of most organic compounds. Consequently‚ our understanding of organic chemistry must have‚ as a foundation‚ an appreciation of the electronic structure and properties of these elements. The truncated periodic table shown above provides the orbital electronic structure for the first eighteen elements (hydrogen through argon). According to the Aufbau principle‚ the electrons of an atom occupy quantum levels or orbitals starting

Importance of Organic Foods The definition of organic agriculture is farming with the use of synthetic chemicals. After World War II‚ larger and increasingly automated farms‚ known as "factory farms‚" put the synthetic fertilizers‚ pesticides and herbicides developed in the 1920s into widespread use. They found that more crops could be produced mass produced. What they did not realize were the dangers of using these chemicals and the effects they would have on the environment and human health

SYNTHETIC EXPLOITATION OF ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting
