Question

Raschig’s process is employed for the commercial preparation of:
$A)$Ethyl chloride
$B)$Grignard’s reagent
$C)$Hydroxylamine
$D)$Ethanol

Answer 1

Hint: Raschig’s reaction is an industrial method for the production of chlorobenzene from benzene. Benzene is the raw material required for this process.
Complete step by step answer:

Complete step by step solution:
Raschig’s process is employed for the commercial production preparation of hydroxylamine
The primary step in this cycle, protected by Raschig, is the decrease of nitrite with bisulfite towards hydroxylamine disulfonate, which is hydrolyzed to hydroxylammonium sulfate. The industrially utilized Raschig measure comprises the accompanying advances, ammonium carbonate reaction is set up by responding to alkali, carbon dioxide and water. An alkali arrangement of ammonium nitrite is shaped by reacting ammonium carbonate reaction with nitrogen oxides. Ammonium nitrite is changed over to hydroxylamine disulfonate with sulfur dioxide. Hydroxylamine disulfonate is hydrolyzed to hydroxylammonium sulfate.
The Raschig–Hookers measure is a chemical process for the synthesis of phenol. The fundamental strides in this interaction are the production of chlorobenzene from benzene, hydrochloric acid and oxygen, and the resulting hydrolysis of chlorobenzene to phenol. The initial step utilizes either a copper or iron chloride impetus and opens the materials to air at ${400^ \circ }C$. In the subsequent advance, the subsequent chlorobenzene is acquainted with steam at ${450^ \circ }C$over a silicon impetus that hydrolyses the chlorobenzene, giving phenol and hydrogen chloride that would then be able to be reused back to the initial step. Because of the two-stage nature, the Raschig–Hooker cycle can be utilized to deliver either chlorobenzene or phenol.

The correct answer is $C)$.

Note:
Remember the capacity to reuse the hydrogen chloride made the Raschig–Hooker measure desirable over the Dow and Bayer measure. The response, nonetheless, happens at exceptionally high temperatures in an acidic climate with hydrogen chloride fume and in this manner, the modern setting should utilize profoundly highly corrosion resistance for the reaction.
