Question

Chloroform reacts with $Conc.HN{O_3}$ to give X. This X is used as.
A. War gas.
B. Insecticide.
C. Drug.
D. Preservative.

Answer 1

We know Chloropicrin, is a synthetic compound at present utilized as a wide range antimicrobial, fungicide, herbicide, bug spray, and nematicide. The chemical formula of the compound is $C{l_3}CN{O_2}$.

Complete step by step answer: We must remember that the hydrogen of the chloroform is supplanted by nitro bunch when it is treated with concentrated nitric corrosive. The item framed is chloropicrin or trichloronitro methane or nitro chloroform. It is a fluid, toxic and utilized as a bug spray and a war gas and as Nitric corrosive Chloropicrin (Tear gas). We can write the chemical equation for the reaction of chloroform$\left( {CHC{l_3}} \right)$ with concentrated nitric acid as,
$CHC{l_3}{\text{ }} + {\text{ }}HON{O_2}{\text{ }}\xrightarrow{{}}{\text{ }}CN{O_2}C{l_3}{\text{ }} + {\text{ }}{H_2}O$
We have to remember that in horticulture, chloropicrin is infused into soil before planting a harvest so as to clean the dirt of a wide range of organisms, microorganisms, bugs, and other hurtful vermin. It is ordinarily utilized as an independent treatment or in blend/co-definition with methyl bromide and 1,3-Dichloropropene.
So, the correct answer is “Option A & B”.

Additional Information:
We have to remember that the chloropicrin's compound equation is $C{l_3}CN{O_2}$ and its atomic weight is$164.38grams/mole$.Pure chloropicrin is a dreary fluid, with a breaking point of $112^\circ C$ .Chloropicrin is sparingly dissolvable in water with solvency of $2000mg/L$at $25^\circ C$. It is unpredictable; with a fume weight of $23.2$ millimeters of mercury at $25^\circ C$, the relating Henry's law steady is $0.00251$ air cubic meter per mole. The octanol-water parcel coefficient of chloropicrin is assessed to be $269$ . Its dirt adsorption coefficient is$25c{m^3}/g$.

Note:
Utilized as a preplant soil treatment measure, chloropicrin smothers soil borne pathogenic parasites and a few nematodes and creepy crawlies. With a half-existence of hours to days, it is totally processed by soil living beings before the yield is planted, making it sheltered and proficient. In opposition to mainstream thinking, chloropicrin doesn't clean soil and doesn't exhaust the ozone layer, as the compound is wrecked by daylight. Moreover, chloropicrin has never been found in groundwater, because of its low dissolvability.
