For an ionic solid of the genral formula `AB` and coordination number `6` , the value of the radius ratio will be

A

less then `0.225`

B

in bwetween `0.225` and `0.732`

C

between `0.414` and `0.732`

D

greater then `0.732`

Text Solution

Verified by Experts

The correct Answer is:
A
Ionic solid having `C.N = 6` cations in octabudral hles
Hence `0.414 lt((r_(+))/(r_(-)))lt 0.732`
