halogens use

The presence of halogens in any organic compound is detected by using sodium extract (Lassaigne's extract) with silver nitrate as follow..

Alkenes react with halogens to form dihaloalkanes. The order of reactivity is, chlorine > bromine > iodine. Simply mixing together the two reactants, usually in an inert solvent like carbon tetrachloride, best carries out the reaction. Alkene ..

Chloroform reacts with primary amines (both aliphatic and aromatic) and alcoholic caustic potash, to give isocyanide compound, which is commonly known as carbylamine. It has an extremely unpleasant smell and is used as a test for primary amines. ..

The halogen atom is replaced by cyano group on heating with anhydrous cuprous cyanide in the presence of pyridine or dimethylformamide (DMF)...

Chloroform combines with acetone in the presence of potassium hydroxide to give chloretone, which is used as a sleep producing (hypnotic) drug...

In the presence of air or light chloroform is slowly oxidized into a poisonous compound phosgene (carbonyl chloride)...

The monohalogen derivatives of alkanes are called alkyl halides. Their names are derived by naming the attached alkyl group to halogen and adding the name of the halide. For example, The prefix n- is used for alkyl group having continuous chain of C-atoms with no branching...

This method is used to prepare fluoroarenes by treating benzene diazonium chloride with fluoroboric acid. The reaction produces diazonium fluoroborate which, on heating, produces fluorobenzene...
