Coupling Reaction of Phenol

By HARI -
When an ice cold solution of phenol is treated with an ice cold solution of benzene diazonium chloride in mildly alkaline medium p_hydroxy azo benzene (Azo dye) is formed. This reaction is called coupling reaction.

reactions of benzene diazonium salt

By HARI -
Replacement reaction of benzene diazonium chloride by  cyanide ion   Benzene diazonium salt with cuprous cyanides in presence of potassium cyanide gives cyanobenzene (benzene nitrile)Cyanobenzene formed can be converted to benzoic acid by hydrolysis. This method is used to introduce-COOH group in aromatic ring. Replacement reaction of benzene diazonium chloride by  OH - ion Aromatic diazonium salts are unstable and hence easily decompose when warned with water forming phenol and nitrogen gas. Replacement reaction of benzene diazonium chloride by  hydrogen Reducing agents like hypo phosphorous acid can replace diazonium group with hydrogen atom producing arene.

Reaction of Ether with Hydrogen Iodide (HI)

Chemical properties of Ethers (With HI) On heating with concentrated Hydrogen iodide (HI) the C-O bond in ethers breaks forming alcohol and alkyl iodide. For example, C 2 H 5 -O-C 2 H 5 + HI ------------> C 2 H 5 - I + C 2 H 5 OH On boiling with excess of concentrated Hydrogen iodide (HI), Alkyl iodide is formed. C 2 H 5 -O-C 2 H 5 + 2HI ------------> 2C 2 H 5 I + H 2 O In the case of mixed ethers with two different alkyl groups, the site of cleavage and hence the alcohol and alkyl iodide that form depend on the nature of the alkyl groups. When one group is methyl and the other is primary or secondary alkyl group, it is the lower alkyl group that forms alkyl iodide due to steric factors. For Example, When one group is methyl and the other alkyl group is a tertiary group, the halide formed is a tertiary group, the halide formed is a tertiary halide. For Example, It is because the attack by I- takes place at that carbon of alkyl group, which has a greater electron pus...

Reaction of Ether with Sulphuric Acid

Chemical Properties of Ethers (with H 2 SO 4 ) On heating with dilute sulfuric acid under pressure, ethers are hydrolysed to alcohols. For example, C 2 H 5 OC 2 H 5 + H 2 O ----( dil.H2so4,high pressure )-----> 2C 2 H 5 OH Mixed ethers under similar conditions give a mixture of alcohols. CH 3 OC 2 H 5 + H 2 O ------( dil.H2so4,high pressure )------>C 2 H 5 OH + CH 3 OH But if concentrated sulfuric acid is used, then the products are alcohol and alkyl hydrogen sulphate. C 2 H 5 OC 2 H 5 (Diethyl ether) -----( heat, conc. H2SO4 )-----> C 2 H 5 OH (ethanol)+ C 2 H 5 OSO 2 OH (ethyl hydrogen sulphate) Ethers containing secondary and tertiary alkyl groups form alkenes with conc. sulphuric acid.
