Hint: The Raschig–Hooker measure is a substance cycle for the creation of phenol. In the subsequent advance, the subsequent chlorobenzene is acquainted with steam at 450℃ 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.
Complete step by step answer:
As we know, Hydrazine is an inorganic compound with the substance recipe\[{N_2}{H_4}\]. It is a straightforward pnictogen hydride, and is a drab combustible fluid with an alkali like smell. Hydrazine is profoundly harmful except if dealt with in arrangement as e.g., hydrazine hydrate \[\left( {N{H_2}N{H_2}{\text{ }}\cdot{\text{ }}x{H_2}O} \right)\].Hydrazine is fundamentally utilized as a frothing specialist in getting ready polymer froths, however applications likewise incorporate its uses as a forerunner to polymerization impetuses, drugs, and agrochemicals, just as a drawn out storable charge for in-space rocket drive.
\[2N{H_3}\; + {\text{ }}NaOCl{\text{ }} \to {\text{ }}{N_2}{H_4}\; + {\text{ }}NaCl{\text{ }} + {\text{ }}{H_2}O\]
\[N{H_3}\; + {\text{ }}OC{l^ - }\; \to {\text{ }}N{H_2}Cl{\text{ }} + {\text{ }}O{H^ - }\]
Hydrazine is utilized inside both atomic and ordinary electrical force plant steam cycles as an oxygen scrounger to control groupings of disintegrated oxygen with an end goal to decrease erosion. Hydrazines allude to a class of natural substances determined by supplanting at least one hydrogen molecules in hydrazine with a natural gathering
\[N{H_2}Cl{\text{ }} + {\text{ }}N{H_3}\; + {\text{ }}NaOH{\text{ }} \to {\text{ }}{N_2}{H_4}\; + {\text{ }}NaCl{\text{ }} + {\text{ }}{H_2}O\]
At the point when hydrazine is added to water, two diverse hydrazinium salts are gotten. \[{N_2}{H_5}^ + \]salts can be confined, yet \[{N_2}{H_6}^{2 + }\]salts are regularly widely hydrolyzed.
$
{N_2}{H_4}\; + {\text{ }}{H_2}O{\text{ }} \rightleftharpoons {\text{ }}{N_2}{H_5}^ + \; + {\text{ }}O{H^ - } \\
{N_2}{H_5}^ + \; + {\text{ }}{H_2}O{\text{ }} \rightleftharpoons {\text{ }}{N_2}{H_6}^{2 + }\; + {\text{ }}O{H^ - } \\
$
Hydrazine is best set up by the Raschig cycle, which includes the response of a watery soluble alkali arrangement with sodium hypochlorite, (NaOCl). Right now, most hydrazine is created by the ketazine cycle, which is a variety of the Raschig cycle. Smelling salts is oxidized by chlorine or chloramines within the sight of an aliphatic ketone, generally \[{(C{H_3})_2}CO\]. The subsequent ketazine is then hydrolyzed to hydrazine.
\[2N{H_3} + NaOCl \to {N_2}{H_4} + NaCl + {H_{2}}O\]
So, the correct answer is Option a.
Note: Sodium Hypochlorite is a chlorine compound regularly utilized as a disinfectant or a dying specialist. Sodium hypochlorite in \[0.5\% {\text{ }}w/v\] arrangement is called Dakin's answer, and is utilized as a germ-free to clean contaminated effective injuries. Sodium hypochlorite is commonly utilized in water at different focuses. Albeit accessible, strong sodium hypochlorite isn't industrially utilized. Sodium hypochlorite arrangements are clear, greenish to yellow fluids with a smell of chlorine.
