JEE Main 2024 — Chemistry In Everyday Life Question with Solution

The matching for each compound with its respective use is based on their known applications:

• Iodoform is a compound known for its application as an antiseptic. It has been used historically in medical applications for the treatment of wounds due to its antimicrobial properties. Hence, Iodoform matches with III. Antiseptic.
• Carbon Tetrachloride was widely used as a fire extinguishing agent due to its property of being a non-flammable liquid that can suffocate fires. However, its use has been significantly reduced in most countries because of its adverse health and environmental impacts. Carbon Tetrachloride matches with I. Fire extinguisher.
• CFCs (Chlorofluorocarbons) have been used as refrigerants in air conditioning and refrigeration systems. Their capacity to absorb heat makes them suitable for this purpose. Unfortunately, their harmful effects on the ozone layer have led to their phase-out under global agreements like the Montreal Protocol. Therefore, CFC matches with IV. Refrigerants.
• DDT (Dichlorodiphenyltrichloroethane) is known for its use as an insecticide. It was widely used to control mosquito populations and other agricultural pests. However, due to environmental and health concerns, its use has been banned or severely restricted in many countries. DDT matches with II. Insecticide.

Thus, the correct option is Option B: A-III, B-I, C-IV, D-II.
