e1 elimination reactions

The reactions in which a small molecule is removed from adjacent carbon atoms resulting in the formation of additional (multiple) bond between them are called elimination reactions. For example,..

Elimination Reactions (Dehydrohalogenation) - Haloalkanes undergo elimination of hydrogen halide (HX) when boiled with alcoholic solution of potassium hydroxide, resulting in the formation of alkenes. As the hydrogen atom present at b -position of haloalkane (i.eh..

Hoffmann's Bromamide reaction - Acid amides on reaction with bromine in the presence of alkalis at about 343 K give primary amine..

Reaction with Nitrous Acid - The three classes of amines react differently with nitrous acid. Nitrous acid is a source of electrophilic nitrosonium ion (O = N + ), which reacts with amines. Nitrous acid being unstable is generated in situ from a mineral acid and sodium nitrite. Primary ar..

Monomers react with each other with elimination of small molecules like water, methanol and ammonia to form polymers. Example: Nylon is a condensation polym..

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..

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. Reaction..

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..

The nitrogenous waste materials produced in the animal body due to metabolic reactions are of no use to the cell. These waste materials if allowed to accumulate in the body, may become toxic. Therefore, they must be removed from the body. The process of elimination of meta..

Introduction - The nitrogenous waste materials produced in the animal body due to metabolic reactions are of no use to the cell. These waste materials if allowed to accumulate in the body, may become toxic. Therefore, they must be removed from the body. The process of elimination..
