Multiple choice

Which of the following combinations of ‘limiting radius ratio: coordination number- shape’ is not correctly matched?

  1. < 0.155 : 2- linear

  2. 0.155 - 0.225 : 3- triangular planar

  3. 0.225 – 0.414 : 4- tetrahedral

  4. 0.414 – 0.732 : 4- square planar

  5. 0.732 – 0.999 : 6- octahedral

E Correct answer
Explanation

For coordination number 6 the shape is octahedral with limiting radius ratio of 0.414 – 0.732. The radius ratio 0.732 – 0.999 is limiting for coordination number 8 with cubic shape.
