QQuestion
A hydrocarbon in the substitution reaction with chlorine in diffused sunlight forms methyl chloride in the first step. What is the hydrocarbon ? Write balanced chemical equation for the first step of the reaction. Mention one use of the hydrocarbon. [1 + 1 +1]
OR
What is the industrial source of LPG? Write one use of each of acetic acid and poly (tetrafluoroethylene). [1 + 2]
✓Answer
The hydrocarbon is methane (CH4).
Balanced Chemical Equation for the First Step:
CH4+ Cl2 {\overset{\text{diffused sunlight}}{\longrightarrow}} CH3 + HCl
In this reaction, methane reacts with chlorine to form methyl chloride (CH3Cl) and hydrogen chloride (HCl).
Use of Methane:
Methane is widely used as a fuel in domestic and industrial applications due to its high energy content.
OR
The primary industrial sources of LPG (Liquefied Petroleum Gas) are natural gas processing and crude oil refining.
Uses:
- Acetic Acid: Used as a preservative and flavouring agent in food (e.g., vinegar).
- Poly (tetrafluoroethylene): Commonly known as Teflon, it is used as a non-stick coating for cookware.
