Question

When chloroform is treated with conc. \[{\rm{HN}}{{\rm{O}}_{\rm{3}}}\] it gives
A. \[{\rm{CHC}}{{\rm{l}}_{\rm{2}}}{\rm{N}}{{\rm{O}}_{\rm{2}}}\]
B. \[{\rm{CC}}{{\rm{l}}_{\rm{3}}}{\rm{N}}{{\rm{O}}_{\rm{2}}}\]
C. \[{\rm{CHC}}{{\rm{l}}_{\rm{2}}}{\rm{HN}}{{\rm{O}}_{\rm{3}}}\]
D. None of these

Answer 1

Hint: Chloroform is chemical compound whose chemical formula is \[{\rm{CHC}}{{\rm{l}}_{\rm{3}}}\] . It is a liquid that transforms into the liquid quickly. It has no colour. It can cause harm to the skin, eyes, kidneys, liver, and nervous system.

Complete Step by Step Solution:
Let’s understand the reaction of chloroform and nitric acid. When chloroform undergoes a reaction with nitric acid, the formation of chloropicrin takes place. The chemical reaction is as follows:
\[{\rm{CHC}}{{\rm{l}}_{\rm{3}}} + {\rm{HN}}{{\rm{O}}_{\rm{3}}} \to \mathop {{\rm{CC}}{{\rm{l}}_{\rm{3}}}{\rm{N}}{{\rm{O}}_{\rm{2}}}}\limits_{{\rm{Chloropicrin}}} + {{\rm{H}}_{\rm{2}}}{\rm{O}}\]

Let’s discuss the uses of chloropicrin:
Chloropicrin is a chemical compound used as a fungicide, antimicrobial, herbicide, and nematicide. The other names of chloropicrin are nitro chloroform or trichloronitro methane. It is a fluid whose nature is toxic and thus finds many applications in war gas, bug spray, etc. It is also called tear gas. In agriculture also, chloropicrin is widely used.

Before harvest, chloropicrin is infused into the soil before harvest to clean the dirt of microorganisms, harmful vermin, and bugs, etc. After some days, chloropicrin is totally processed by the microorganisms. It does not get dissolved in water therefore, it is not found in groundwater. It is also used in the medical industry.
Hence, option B is right.

Note: There are many applications of chloroform such as making floor polishes, adhesives, resins, oils, rubber, etc. It is also used to manufacture a refrigerant, fluorocarbon-22. In 1900, it was used as anaesthetic to reduce pain. Through inhalation or ingestion, chloroform is absorbed into our body. Exposure to chloroform causes cancer.
