The limiting radius ratio (r_+/r_-) for octahedral coordination is:

JEE Main Chemistry question

Not in JEE Main or NEET syllabus

The limiting radius ratio for octahedral coordination is:

(A)0.414Correct
(B)0.225
(C)0.02
(D)None of these

Answer: (A)

Solution

By the radius-ratio rule, a coordination number of 6 (octahedral geometry) first becomes geometrically possible once (up to 0.732, beyond which 8-coordination takes over). A ratio of 0.225 is
