Approved Tutor Answer7 Years agojust put zinc dust to phenol , you’ll get benzene
phenol + zinc dust ------------> benzene + ZnO
hope that helps.......................

Phenol can be converted to benzene by using strong reducing agents like Zn dust with strong heating.
When strongly heated,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 Carbon 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.THe required product benzene is obtained
THe reaction proceeds as follows: Zn+2C6H5OH→2C6H6+Zn(OH)2
