Assertion (A) : In sodium chloride crystal, `Na^(o+)` ions occupy `OVs` while `Cl^(ɵ)` ions occupy vertices of octahedron.
Reason (R ) : The radius ratio of `Na^(o+) : Cl^(ɵ)` lies between `0.4` and `0.7`.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true bur reason is false

D

If assertion is false bur reason is true

Text Solution

Verified by Experts

The correct Answer is:
d

Correct assertion `Na^(o+)` ions occupy all `OVs` but `CI` ions occupy lattice points (coener + face centers)
Reason is correct
For `OV, r_(o+) + r_(Theta) = 0.414 - 0.732`
