These questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: The number of unpaired electrons present in `[CuCl_2]^(-)` complex is zero.
Reason: The complex is linear in the solid state with sp-hybridization.

Options

A. (a) If both assertion and reason are true and the reason are true and reason is the correct explanation of the assertion.
B. (b) If both assertion and reason are true and reason is not the correct explanation of the assertion.
C. (c) If assertion is true but reason is false.
D. (d) If assertion is false but reason is true.

Answer

C

Explanation

Correction Reason: 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.
