Question

Identify the incorrect pair from the following:

• A. Fluorspar - \( \text{BF}_3 \)
• B. Cryolite - \( \text{Na}_3\text{AlF}_6 \)
• C. Fluoroapatite - \( 3\text{Ca}_3(\text{PO}_4)_2 \cdot \text{CaF}_2 \)
• D. Carnallite - \( \text{KCl} \cdot \text{MgCl}_2 \cdot 6\text{H}_2\text{O} \)

Answer 1

The Correct Option is A

Fluorspar is actually CaF₂, not BF₃. BF₃ does not represent Fluorspar, which makes option (1) incorrect.

So, the correct answer is : Option (1)
