Answer»

Statement-1 is True, Statement-2 is True , Statement-2 is a correct explanation for Statement-2
Statement-1 is True, Statement is 2 is True , Statement-2 is NOT a correct explanation for Statement-2
Statement-1 is True, Statement-2 is False
Statement-1 is False, Statement-2 is True

Solution :Correct Statement-2. The complex, `[CuCl_(2)]^(-)` (as WELL as [`CuCl_(3)]^(2-)` and `[CuCl_(4)]^(2-)`) are tetrahedral in the solid state. In `KCuCl_(2)`, there are chains in which Cu is tetrahedrally surrounded by Cl with simple UNITS joined into a chain by shared halide IONS.
