What happens when phenol is heated with zinc powder

Hint: Distillation of phenol with zinc-dust gives benzene and ZnO as a side-product. The reaction proceeds as follows: - The phenol gets converted into phenoxide ion and thus the released proton accepts an electron from Zn forming hydrogen radical. because of the heating, there's homolytic fission of C of the phenyl ring and O−. Complete answer: When phenol is heated with zn dust reduction of phenol occurs and it gets converted into Benzene with ZnO as a by-product. Here's the reaction: Phenol+ Zn $\Rightarrow$ Benzene + ZnO And here's the detailed mechanism; Zn shows an oxidation state of +2. The phenol gets converted into phenoxide ion and the proton thus released accepts an electron from Zn forming H radical. Also thanks to the heating there's homolytic fission of C of phenyl ring and O- The O- thus formed accepts an electron from Zn and forms an oxide ion. In this way zinc forms flowers of zinc and phenyl radical thus forms a bond with H radical. However, the yield of this reaction used for benzene formation is lower. Zinc dust is used to manufacture paints and coatings that resist corrosion when applied to structures or surfaces that are vulnerable to harsh environmental conditions. Note: Most zinc is used to galvanise other metals, like iron, to prevent rusting. Galvanised steel is used for car bodies, streetlight posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important within the car , electrical a...

When phenol is heated with zn dust reduction of phenol occurs and it gets converted into Benzene with ZnO as a by-product. 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. How phenol reacts with zinc? When phenol reacts with zinc dust ( at higher temperature) the phenol convert’s to phenoxide ion and a proton. This proton accepts an electron from Zn hence results in H radical. Hence it results in the formation of ZnO . And phenoxide ion convert’s to benzene. When phenol is treated with zinc the product is? benzene When phenol is subjected to distillation in the presence of zinc dust, the product formed is benzene. READ: What to say if a girl asks why you want to meet her? When salicylic acid is heated with zinc dust the product obtained is? benzoic acid OH group (phenolic), hence salicylic acid gives benzoic acid on heating with Zn-powder. When phenol is treated with chcl3 and NaOH the product formed is? When phenol is treated with CHCl3 and NaOH the product formed is salicylaldehyde, this reaction is known as Reimer-Tiemann reaction. When Sulphuric acid is heated with zinc dust What is the main product? When dilute sulphuric acid is poured on zinc granules, then zinc being more reactive than hydrogen displaces it from the acid and forms zinc sulphate and hydrogen gas. When sa...
