Match List-I with the List-IIList-I
(Compound) List-II
(Uses) (A) Iodoform (I) Fire extinguisher (B) Carbon
tetrachloride (II) Insecticide (C) CFC (III) Antiseptic (D) DDT (IV) Refrigerants
Choose the correct answer from the options given below:
| List-I (Compound) | List-II (Uses) |
|---|---|
| (A) Iodoform | (I) Fire extinguisher |
| (B) Carbon tetrachloride | (II) Insecticide |
| (C) CFC | (III) Antiseptic |
| (D) DDT | (IV) Refrigerants |
- A-I, B-II, C-III, D-IV
- A-III, B-II, C-IV, D-I
- A-III, B-I, C-IV, D-II
- A-II, B-IV, C-I, D-III
The Correct Option is C
Approach Solution - 1
To correctly match the compounds in List-I with their respective uses in List-II, we must understand the specific characteristics and applications of each compound:
- Iodoform (A) is known for its antiseptic properties. It has been used historically in medicine as a disinfectant. Therefore, the correct match is III - Antiseptic.
- Carbon tetrachloride (B) was once widely used in fire extinguishers due to its non-flammable properties. Because of its toxicity and adverse health effects, its use is now limited. The correct match is I - Fire extinguisher.
- CFC (Chlorofluorocarbons) (C) are compounds known for their role as refrigerants. They are used in air conditioning and refrigeration systems but are being phased out due to their ozone-depleting effects. The correct match is IV - Refrigerants.
- DDT (Dichloro-Diphenyl-Trichloroethane) (D) is a well-known pesticide and insecticide. It was widely used to control mosquito populations but is now banned in many countries due to environmental and health concerns. The correct match is II - Insecticide.
Based on the above explanations, the correct matching pattern is:
- A-III (Iodoform - Antiseptic)
- B-I (Carbon tetrachloride - Fire extinguisher)
- C-IV (CFC - Refrigerants)
- D-II (DDT - Insecticide)
Thus, the correct answer is: A-III, B-I, C-IV, D-II.
Approach Solution -2
Iodoform $\rightarrow$ Antiseptic
CCl$_4$ $\rightarrow$ Fire extinguisher
CFC $\rightarrow$ Refrigerants
DDT $\rightarrow$ Insecticide
Thus, the correct match is:
\[\boxed{\text{A-III, B-I, C-IV, D-II}}\]
