1.	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 assertionB. If both assertion and reason are true but reason is not the correct explanation of the assertionC. If assertion is true bur reason is falseD. If assertion is false bur reason is true
Answer» Correct Answer - b Correct explanation `Na^(+)` ions can be placed only in the octabedral (Terahedral viods are ion small to accommodate then)
