How is benzophenone formed?
Benzophenone is produced by the copper-catalyzed oxidation of diphenylmethane with air. A laboratory route involves the reaction of benzene with carbon tetrachloride followed by hydrolysis of the resulting diphenyldichloromethane.
How can you reduce benzaldehyde to benzene?
When benzaldehyde is oxidized in the presence of acidified potassium permanganate, it results in the formation of benzoic acid. When benzoic acid is reacted with soda lime (mixture of NaOH and CaO) with heat, it results in the formation of benzene.
How do you convert benzaldehyde to acetophenone?
In order to make acetophenone from benzaldehyde, the following reactions take place. Benzaldehyde undergoes oxidation in the presence of potassium permanganate and sulphuric acid to form benzoic acid. Benzoic acid further reacts with sodium hydroxide to produce sodium salt of benzoic acid that is sodium benzoate.
How do you convert toluene to benzaldehyde?
Benzaldehyde is also formed by oxidation of toluene with chromic oxide in acetic anhydride. Benzaldehyde reacts with acetic anhydride to form benzylidene diacetate which on hydrolysis with alkali or an acid yields benzaldehyde.

How benzaldehyde is prepared from toluene write only one method?
Industrially, benzaldehyde is made by a process in which toluene is treated with chlorine to form benzal chloride, followed by treatment of benzal chloride with water. Benzaldehyde is readily oxidized to benzoic acid and is converted to addition products by hydrocyanic acid or sodium bisulfite.
How benzaldehyde is prepared from toluene and benzene?
We can see that in this reaction Benzaldehyde is formed by the oxidation of toluene with chromic oxide in acetic anhydride. Basically, Benzaldehyde is found to react with the acetic anhydride to form benzylidene diacetate. This on further hydrolysis with acid or with an alkali produces Benzaldehyde.
