1.	b] Name the product formed when phenol vapours are passed over heated zidust. Write the chemical equation.
Answer» When phenol is heated with zn dust reduction of phenol occurs and it gets converted into Benzene with ZnO as a by-product.Phenol+Zn⟶Benzene+ZnO mechanism; Zn shows an oxidation state of +2. The phenol gets converted into phenoxide ion and proton thus released accepts an electron from Zn forming H radical. Also because of the heating there is homolytic fission of C of phenyl ring and O- The O- thus formed accepts an electron from Zn and forms oxide ion. In this way zinc forms zinc oxide and phenyl radical thus produced forms a bond with H radical. However, the yield of this reaction used for benzene formation is lower.

Answer»

When phenol is heated with zn dust reduction of phenol occurs and it gets converted into Benzene with ZnO as a by-product.Phenol+Zn⟶Benzene+ZnO mechanism;

Zn shows an oxidation state of +2.

The phenol gets converted into phenoxide ion and proton thus released accepts an electron from Zn forming H radical.

Also because of the heating there is homolytic fission of C of phenyl ring and O-

The O- thus formed accepts an electron from Zn and forms oxide ion.

In this way zinc forms zinc oxide and phenyl radical thus produced forms a bond with H radical.

However, the yield of this reaction used for benzene formation is lower.
