mechanism of organic reaction

Mechanism of Reaction - A balanced chemical equation represents the overall result of a chemical reaction. However, at the molecular level, more than one reaction step might be involved. Most reactions can be broken down into a sequence of elementar..

Sonography is based on ultra sound (frequency above 20 KHz). When high frequency sound waves travel forwards, they continue to move until they make contact with an object. Then a certain amount of the sound bounces back. In medical practice, ultra sound of frequency 1 - 15 MHz in beamed into the h..

An organism, may be small unicellular or multicellular. Organisms have a fixed life span and organised life cycle comprising of birth, growth, maturity, old age and death. They are always derived from pre-existing ones through the mechanism of reproduction. The offspr..

Types of Organic Reactions - There are four types of reactions..

The reactions in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or group of atoms are called substitution reaction..

Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In o..

An organic compound containing C, H, N, S and halogens when fused with sodium metal gives the following reactions. (NaSCN) is formed during fusion, which in the presence of excess sodium forms sodium cyanide and sodium sulphide. ..

At the cellular level, growth is the increase in the amount of protoplasm (nuclues + cytoplasm). During growth, the synthesis of complex molecules like proteins nucleic acids and carbohydrates is at a higher rate than the rate at which the complex molecules are broken down. During growth, the anabo..
