Question

Statement 1: The number of unpaired electrons present in $[CuC{l}_2{]}^{-}$ complex is zero..
Statement 2:The complex is linear in the solid state with sp-hybridization

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1.
• B. Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1.
• C. If Statement 1 is true but Statement 2 is false.
• D. If Statement 1 is false but Statement 2 is true.

Answer 1

Answer: (C)

Correct statement 2: The complex, $[CuC{l}_2{]}^{-}$ (as well as $[CuC{l}_3{]}^{2-}$ and $[CuC{l}_4{]}^{2-})$ are tetrahedral in the solid state. In $KCuC{l}_2$, there are chains in which $Cu$ is tetrahedrally surrounded by $Cl$ with simple units joined into a chain by shared halide ions.
