JEE Main 2024 — Chemistry In Everyday Life Question with Solution

Each of the compounds listed in List I has distinct uses. Let's match them correctly with the uses mentioned in List II:

• Carbon tetrachloride (A) was historically used as a cleaning agent, among other things, but due to its toxicity and role in ozone depletion, it is no longer widely used for this purpose; hence it does not match with any of the uses. However, it was previously used in fire extinguishers, so one might think of it in association with (III).


• Methylene chloride (B), also known as dichloromethane, is commonly used as a solvent and paint remover, so it matches with (I).


• DDT (C) is a well-known, though now largely banned, insecticide due to its persistence and bioaccumulation, making it not biodegradable. It matches with (IV).


• Freons (D) is a trade name for a group of halogenated compounds used primarily as refrigerants, so it matches with (II).

Considering these associations, we can match the compounds with their correct uses:

• (A) Carbon tetrachloride - (III) Fire extinguisher
• (B) Methylene chloride - (I) Paint remover
• (C) DDT - (IV) Non-biodegradable insecticide
• (D) Freons - (II) Refrigerators and air conditioners

So, the correct match according to the given options will be:

Option B:
(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
