If R is the radius of the octahedral void and r is the radius of the atom in close packing, then r/R is equal to

A

4.76

B

3.22

C

2.41

D

9.1

Text Solution

Verified by Experts

The correct Answer is:
C
For `O.V,(R )/(r)["i.e. "(r_(+))/(r_(-))(or)(r_("void"))/(r_(-))]=0.414 therefore (r)/(R )=(1)/(0.141)=2.41`
