Statement-2 : The number of octahedral voids is equal to the number of `Cl^(-)` ions in the packing .

A

Statement 1 is True , Statementy -2 True , Statement -2 is a correct explanation for statement -1 .

B

Statement 1 is True , Statement -2 is True , Statement -2 in NOT a correct explanation of statement -1.

C

Statement -1 is True , Statement -2 is False.

D

Statement -1 is False , Statement -2 is True.

The correct Answer is:
d
Correct explanation. ` Na^(+)` ions can be placed only in the octahedral voids. ( Tetrahedral voids are too small to accommodate them).
