Question

A lightning flash through air may result in the formation of __________.
A)$NO$
B)$HN{{O}_{2}}$
C)$HN{{O}_{3}}$
D)${{N}_{2}}{{H}_{5}}$

Answer 1

Hint The answer here is dependent on the general environmental chemistry topic where the answer can be approached when you write a balanced chemical equation of the reaction between oxygen and compound of nitrogen.

Complete step – by – step answer:
In the lower classes of chemistry, we have dealt with some of the general topics which also include the environmental chemistry where the topic deals with the changes happening in the environment and also some of the chemical reaction which takes place in nature naturally.
Let us now see what happens when a flash of light strikes the atmosphere that is by writing the chemical reaction taking place.
- Atmosphere consists of various mixtures of gases and the maximum percentage is of nitrogen and several amounts of oxygen, some of the chloro – fluoro carbons and also nitrates and sulphates.
- Lightening occurs in nature which is nothing but is the electrical discharge caused due to the imbalances between storm clouds and the ground.
- Ozone formation takes place because of lightning and at higher temperatures lightning generates energy which is very high and is enough for the nitrogen and oxygen in air to combine forming nitrogen oxide.
Thus, this fact can be written in the form of a chemical equation as,
$NO+\frac{1}{2}{{O}_{2}}\to N{{O}_{2}}$
$3N{{O}_{2}}+{{H}_{2}}O\to 2HN{{O}_{3}}+NO$
Along with the formation of nitrogen oxide and nitric acid, a small amount of $HN{{O}_{2}}$ is also formed.

Therefore, the correct answer is option A), B) and C)

Note: Note that the lightning when occurs, it splits the atmospheric diatom of oxygen into individual oxygen atoms and these can further combine with other oxygen molecules to form ozone.
