MHT CET Chemistry question
Not in JEE Main or NEET syllabus
A mineral having the formula crystallize in cubic close packed lattice with the A atoms occupying the lattice points. The coordination number of atoms of A, atoms of B and the fraction of the tetrahedral sites occupied by B are respectively
Answer: (B)
Solution
With A at the ccp lattice points (4 per cell) and AB2 requiring 8 B atoms, B occupies all 8 tetrahedral sites (100%), so
