Question

Match List - I with List - II. 

• A. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
• B. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
• C. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
• D. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Hint:

Common ores to remember: Bauxite (Al), Hematite/Magnetite (Fe), Copper Pyrites (Cu), Zinc Blende (Zn).

Answer 1

The Correct Option is D

To solve the given matching question, we need to correctly pair items from List-I with corresponding items in List-II, based on acceptable associations in the field of chemistry. Let's analyze each pair:

1. Aluminium and Kaolinite: Kaolinite is a clay mineral, typically represented by the chemical formula Al₂Si₂O₅(OH)₄, which is a source of aluminium. Therefore, Aluminium matches with Kaolinite (a-iii).
2. Iron and Siderite: Siderite is iron carbonate (FeCO₃) and is an ore of iron. So, Iron correctly matches with Siderite (b-i).
3. Copper and Malachite: Malachite is a copper carbonate hydroxide mineral (Cu₂(CO₃)₂(OH)₂), thus associating Copper with Malachite (c-iv).
4. Zinc and Calamine: Calamine is a mineral containing zinc, primarily zinc carbonate (ZnCO₃) and zinc silicate. Thus, Zinc matches with Calamine (d-ii).

Therefore, the correct option is:

(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

This option aligns with the known associations between the metals and their respective ores.
