|---|---|
| (A) CCl4 | (i) Insecticide |
| (B) CF2Cl2 | (ii) Refrigerant |
| (C) CHI3 | (iii) Antiseptic for wounds |
| (D) CH2Cl2 | (iv) Propellant for aerosols |
Each compound is matched to its application based on its chemical properties and uses:
• CCl4 (Carbon tetrachloride) was historically used as an insecticide due to its toxic properties, though its use is now restricted.
• CF2Cl2 (Dichlorodifluoromethane) is widely used as a refrigerant because of its stable and non-reactive nature.
• CHI3 (Iodoform) is used as an antiseptic for wounds, known for its distinctive odor.
• CH2Cl2 (Dichloromethane) is a volatile compound commonly used as a propellant in aerosols.
