Answer:
Benzene diazonium chloride on reaction with phenol in a basic medium gives p-Hydroxy azobenzene. This is an example of a coupling reaction.
Explanation:
- The structure of Benzene diazonium chloride is
- And the structure of p-Hydroxy azobenzene is,
- Benzene diazonium chloride has the chemical formula C6H5ClN2. Benzene diazonium chloride is a salt of a chloride and diazonium cation. Benzene diazonium chloride exists as a colorless solid and it is soluble in polar solvents such as in water. It acts as the parent member of the aryl diazonium compounds. This compound is widely used in organic chemistry. As this salt is unstable, it is not available commercially but is prepared according to demand. p-hydroxyazobenzene has the chemical formula Cl2H10N20 and has the atomic number 198.221. It has a density of 1.13g/cm3, has a boiling point of 369.812oC, and has a refractive index of 1.596.
- The mechanism for the reaction of benzene diazonium chloride on reaction with phenol can be given as follows:
