How will you convert phenol to anisole?
How will you convert phenol to anisole?
Complete answer: (A)Phenol to anisole: First let us see the structures of phenol and anisole. In this what we need to do is replace the H atom from –OH group to CH3. This can be done by first reacting phenol with a base NaOH and then treating it with an alkyl halide like CH3−Br .
Which of the following reagents are required for conversion of phenol to anisole?
Methyl iodide, like dimethyl sulfate, releases $C{{H}_{3}}^{+}$ ions in the solution. Thus $C{{H}_{3}}I$ also converts phenol into anisole. From the above statements we can conclude that all the three reagents convert phenol into anisole. Therefore, the correct answer is option (D) i.e. all of these.
How do you convert aniline to phenol?
1 Answer. (i) Aniline is diazotized with nitrous acid (NaNO2 + HCl) at 273-278K to give benzene diazonium chloride which on further treatment with hot water in the presence of mineral acid gives phenol.
How is aspirin converted to phenol?
The salicylic acid reacts with acetic anhydride in presence of sulphuric acid to form acetylated salicylic acid and acetic acid. Therefore, we can convert phenol to aspirin by treating phenol with sodium hydroxide and carbon dioxide in an acidic medium. Then treated the product salicylic acid with acetic anhydride.
How do you convert aniline to anisole?
Answer: Phenyl methyl ether. It can be prepared by treating phenol first with a base like NaOH to form phenoxide ion. The phenoxide ion will then substitute the halide of an R-X molecule, to form methyl phenyl ether.
How do you manufacture Anisoles?
Anisole is prepared by methylation of sodium phenoxide with dimethyl sulfate or methyl chloride: 2 C6H5O−Na+ + (CH3O)2SO2 → 2 C6H5OCH3 + Na2SO.
What is the other name of carbolic acid?
Phenol
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile.
How is carbolic acid prepared from cumene?
Answer: Cumene (isopropylbenzene) is oxidised in the presence of air to cumene hydroperoxide. It is converted to phenol and acetone by treating it with dilute acid.
How is aniline converted?
Aniline is an organic compound containing an amine group. It has a 6- carbon atom ring on which the amine group is attached. It can be converted into phenyl isocyanide by a special reaction called carbylamine reaction, which is also a test for isocyanide.
How do you make phenol from paracetamol?
The starting material for the commercial manufacture of paracetamol is phenol, which is nitrated to give a mixture of the ortho and para-nitrotoluene. The o-isomer is removed by steam distillation, and the p-nitro group reduced to a p-amino group. This is then acetylated to give paracetamol.
