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 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:
b

Correct explanation `Na^(+)` ions can be placed only in the octabedral (Terahedral viods are ion small to accommodate then)
