organic chemistry 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,..

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..

>Green chemistry encompasses all aspects and types of chemical process including synthesis, catalysis, analysis, monitoring, separations and reaction conditions, which reduce or eliminate the use or generation of hazardous substances. Green chemistry technolo..

Alkylation - An alkyl halide can react with a primary or secondary amine which acts as a nucleophile. On undergoing nucleophilic substitution, a 1 o amine is converted to a 2 o amine and a 2 o one to a 3 o amine. The 2 o amine being a more powerful nucleophile again reacts with an alkyl halide to f..

From Alkyl halides - Alkyl halides on treatment with ethanolic solution of sodium cyanide or potassium cyanide give alkyl cyanide..

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.e., on the carbon atom next to the one carrying the halogen) is re..
