How do you make M nitrobenzoic acid?
m-Nitrobenzoic acid can be prepared by the nitration of benzoic acid by means of nitric acid,1 a mixture of nitric and sulfuric acids,2 or mixtures of nitrates and sulfuric acid;3 all these methods lead to the production of a mixture containing principally the m-nitrobenzoic acid with a smaller proportion of the ortho …
How do you convert phenol to acid?
Conversion of phenol using zinc dust into benzene. Using (CH3Cl+AlCl3) where aluminium trichloride acts as a Lewis acid catalyst. This reaction is also known as the Friedel-crafts alkylation reaction. The result obtained above is alkyl benzene which on oxidation gives benzoic acid.
How do you convert phenols to carboxylic acids?
1 Answer
- Phenol is converted to benzoic acid by following steps :
- — Conversion of phenol to benzene by treatment with zinc.
- — Friedal craft alkylation of benzene to form toluene.
- — Oxidation of toluene to benzoic acid by potassium permanganate.
How is benzoic acid converted to M nitrobenzoic acid?
Answer : When benzoic acid reacted with nitrating mixture it forms m- nitrobenzoic acid further it treated with SOCl2 it chlorinate the acidic COOH group. And reacting with NaBH4 further it get converted into m-nitroenzyl alcohol.
How will you prepare m nitrobenzoic acid from toluene?
The toluene is then reacted with alkaline potassium permanganate to form benzoic acid. The benzoic acid then undergoes a nitration reaction in presence of nitric acid and sulphuric acid to form m-nitrobenzoic acid.
How is phenol converted into benzoquinone?
Phenol is convert into benzoquinone by carrying its oxidation with sodium dichromate in the presence of conc. H2SO4.
How is phenol converted into salicylaldehyde and salicylic acid?
Phenol to salicyaldehyde: When phenol is treated with chloroform in an aqueous sodium hydroxide solution followed by hydrolysis with acid, salicylaldehyde is formed. If the solvent chloroform (CHCl3) is replaced by carbon tetrachloride (CCl4), salicylic acid is formed.
How is phenol converted into picric acid?
When phenol is treated with hot conc. nitric acid in the presence of conc. sulphuric acid yellow coloured picric acid is produced.
How will you bring about the following conversions I benzene to M Nitroacetophenone?
Answer : After frieadal craft acylation of benzene it will convert into acyl benzene. And further treating with nitrating mixture it forms m-nitroaceto phenone .
How do you convert nitrobenzene to phenol?
Nitrobenzene can be converted in to phenol in two distinct steps. In this step nitrobenzene is reduced by using Sn and conc. HCl to form aniline. In this step aniline is treated with NaNO₂ and HCl in cold condition to form benzene diazonium chloride,which on further treatment with water gives phenol.
How do you convert benzene to benzoic acid?
Benzene is treated with methyl chloride in presence of anhydrous AlCl₃ to form toluene. Step-3:—Oxidation of toluene to form benzoic acid. Toluene is oxidised by alkaline KMnO₄ to form potassium benzoate,which on acid hydrolysis forms benzoic acid.
How to convert toluene to phenol and sodium benzoate?
First toluene is converted to benzoic acid (by KMnO4/OH-). Then it undergoes acid catalysed esterification to form phenyl benzoate. Then, on addition of NaOH, it gives phenol and sodium benzoate.
What is the reaction between nitnitrobenzene and NaNO2 + HCl?
Nitrobenzene on reduction in acidic medium gives Aniline. Obtained Aniline when treated with NaNO2 + HCl at 0–5 degree C gives Benzene Diazonium Chloride. Benzene Diazonium Chloride when treated with water in presence of H2SO4 gives Phenol. Phenol when treated with Zn dust gives Benzene. Benzene on alkylation using CH3Cl gives Toulene.
