Question

(v) Write down the values of radius ratio for tetrahedral and

Octahedral structures.​

Answer 1

Explanation:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Cation-anion radius ratio

Radius Ratio Coordination number Type of void

0.155 - 0.225 3 Triangular Planar

0.225 - 0.414 4 Tetrahedral

0.414 - 0.732 6 Octahedral

0.732 - 1.000 8 Cubic

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Answer 2

Answer:

Explanation:

The Radius Ratio Rule. If we consider an array of anions present in the form of cubic close packing, the tetrahedral holes and the octahedral holes will vary in the sizes. ... Here, Ratio of cation= r, Ratio of anion = R. Thus, Radius ratio = (r/R).
