mechanism of cannizaro reaction

Cannizaro Reaction - Aldehydes which do not have an a -hydrogen atom undergo self oxidation and reduction (i.e., disproportionation) reaction on treatment with concentrated alkali. In this reaction, one molecule of the aldehyde is reduced to alcohol and anoth..

Aldehydes which do not have an a -hydrogen atom undergo self oxidation and reduction (i.e., disproportionation) reaction on treatment with concentrated alkali. In this reaction, one molecule of the aldehyde is reduced to alcohol and another is oxidised to carboxylic acid salt. A..

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..

Morning and evening office hours lead to an increase in vehicular traffic. The emissions of CO, hydrocarbons and oxides of nitrogen increase during these times. These chemicals are also emitted by industries and power plants. NO 2 a good absorber of U.V. ray and visible radiation from the sun, st..

Laws of Chemical Combination - The study of reactions is one of the important areas of Chemistry. There are many aspects of a reaction like the rate of reaction, energy absorbed or evolved, mechanism of a reaction that can be evaluated only with wei..

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. Hence, it is also called Hill's ..

Energy changes in chemical reactions can also take place in forms other than heat, such as light, electricity, mechanical energy, etc. Some common examples are: The burning of petrol or diesel in motor engines of cars, trucks, tractors or buses produces mechanical e..

Measurement of Enthalpy of Reactions - The heat changes in chemical reactions are measured with the help of calorimeters. Depending upon the requirements of experiments different types of calorimeters are used. In general, reactions taking place at constant volume and ..

The study of reactions is one of the important areas of Chemistry. There are many aspects of a reaction like the rate of reaction, energy absorbed or evolved, mechanism of a reaction that can be evaluated only with weight and volume relationships. A..
