Assertion (A) : In the rock salt type structure, all the `OV_(s)` are occupied by `Na^(o+)` ions.
Reason (R ) : Number of `OV_(s) =` Number of `Cl^(ɵ)` ions in the packing.

A

If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`

B

If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`

C

If `(A)` is correct, but `(R)` is incorrect.

D

If both `(A)` is incorrect but `(R)` is correct.

Text Solution

Verified by Experts

The correct Answer is:
B
Correct explanation: `Na^(o+)` ions cen be placed only in `OVs` since `TVs` are too small to accommodate them.
