Nitric acid is used to obtain chloropicrin (trichloronitromethane) by reacting it with chloroform. This reaction is represented by the following chemical equation:
CHCl3 + HNO3 → CCl3NO2 + H2O
Explanation:
Chloropicrin, also known as trichloronitromethane (CCl3NO2), is a chemical compound used as a pesticide, fumigant, and tear gas. It is a yellowish liquid with a pungent odor.
The reaction between chloroform (CHCl3) and nitric acid (HNO3) is an example of a substitution reaction. In this reaction, one of the chlorine atoms in chloroform is replaced by a nitro group (NO2) from nitric acid.
Let's look at the reaction step by step:
1. Formation of chloroform:
Chloroform is a compound formed by the reaction of chlorine (Cl2) with methane (CH4). This reaction occurs in the presence of a catalyst, usually sunlight or heat.
CH4 + 3Cl2 → CHCl3 + 3HCl
2. Reaction with nitric acid:
When chloroform reacts with nitric acid, one of the chlorine atoms in chloroform is replaced by a nitro group (NO2) from nitric acid. This substitution reaction occurs due to the high reactivity of nitric acid.
CHCl3 + HNO3 → CCl3NO2 + H2O
The byproduct of this reaction is water (H2O). The product, chloropicrin (CCl3NO2), is formed as a result of the substitution of chlorine with a nitro group. Chloropicrin is a toxic compound and is commonly used as a pesticide and fumigant.
In conclusion, chloropicrin is obtained by the reaction of chloroform with nitric acid. This reaction involves the substitution of one of the chlorine atoms in chloroform with a nitro group from nitric acid.
