Question

mechanisms of phenol to benzene by using of zinc dust​

Answer 1

Answer:

When phenol is heated with zn dust reduction of phenol occurs and it gets converted into Benzene with ZnO as a by-product. And here's the detailed 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.

Hope it helps...

Answer 2

Answer:

C6H5OH+Zn(dust)+high temp. gives _ C6H6 +ZnO

due to presence of resonance in phenol,

it do not undergoes cleavage of C-O bond
