For an ionic crystal of the general formula

{A^ + }{B^ - }

and co-ordination number 6, the radius ration will be :

View answer and explanation

Correct option: B

Between 0.73 and 0.41

Option B (Between 0.73 and 0.41) is correct. The correct range is between 0.41 and 0.73 because a coordination number of 6 corresponds to an octahedral geometry, and the radius ratio for octahedral geometry falls within that range.
