1.

The CoCl_(2) lattice is

Answer»

BODY centred cubic closed pack
Body centred TETRAGONAL
There are 16 formula units PER unit cell.
The number of molecules which the basis consist is 2

Solution :Choice (a) is correct because in `CaCl_(2)` there is a body centred cubic closed packing.
Choice (B) is correct because there is tetragonal body centre observed.
Choice (c) is also correct because there are 16 `CaCl_(2)` present in one `CaCl_(2)` unit lattice.
