elimination reactions general mechanism

Chemical Properties of Alcohols and Phenols - In alcohols and phenols, -OH group is the functional group. Thus the chemical properties of alcohols generally involve the reactions of -OH group. They can undergo substitution as well as elimination reaction. ..

Electron Displacement in Covalent Bonds - Organic compounds mainly consist of covalent bonds. The displacements of the electron pairs in these covalent bonds may take place either on their own or under the influence of other species. Three types of electron displacements are generally not..

Immunity is defined as the ability to eliminate complexes of protein molecules differing in structure from those present in the healthy animals. There are two kinds of defence mechanism against microbes a) nonspecific defence mechanism b) specific defence mechani..

It is an important laboratory method for the preparation of symmetrical and unsymmetrical ethers. The method involves the treatment of an alkyl halide with sodium or potassium salt of alcohol or phenol. Good results are obtained if the alkyl halide is primary. If a tertiary alkyl halide is used, an..

Processes by which substances are transformed to one or several products are called chemical reactions. Chemical processes that occur in the presence of light, like sunlight, are called photochemical reactions. These processes can occur naturally or under controlled conditions i..

Particulate emissions may be controlled by using mechanical devices that generally work on the basis of the followin..

In general all waves mechanical and electromagnetic (non-mechanical) waves are classified into two types. These are longitudinal waves transverse wave..

It is an equation that relates the true rate of reaction to the concentrations of the reactants raised to some power. Rate law expression serves three purposes. (i) If the composition of the reaction mixture and the rate constant are known, then the rate of the reaction..

It is so called as it takes place only in the presence of sunlight and hence is a light-dependent reaction. Robin Hill, an English biochemist conducted studies on isolated chloroplasts to understand the mechanism of light reactions..

The oxalo succinic acid undergoes decarboxylation to form a -ketoglutaric acid. This reaction is catalysed by decarboxylase. In this reaction one CO 2 is eliminated. Hence the a -ketoglutaric acid has only 5 carbon atom..
