Identify the incorrect pair from the following :

Solution & Explanation

### Core Logic Let's check the mineral formulas assigned to common names: 1. Fluorspar: The formula for fluorspar (also known as fluorite) is CaF_2, not BF_3. This pair is incorrect. 2. Cryolite: Correctly given as Na_3AlF_6. 3. Fluoroapatite: Correctly given as 3Ca_3(PO_4)_2 cdot CaF_2 (or Ca_5(PO_4)_3F). 4. Carnallite: Correctly given as KCl cdot MgCl_2 cdot 6H_2O. ### Step 1: Final Conclusion The incorrect pair is option 1. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Chemistry: General Principles and Processes of Isolation of Elements Class 11 Chemistry: The p Block Elements
