Question

Assertion :Hybridization of $[AuC{l}_4{]}^{\Theta }$ is $s{p}^3$. Reason: Hybridization of Au in above complex compound does not depend upon nature of ligand.

• A. Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
• B. Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1
• C. Statement-1 is true, statement-2 is false.
• D. Statement-1 is false, statement-2 is true.

Answer 1

The correct option is D Statement-1 is false, statement-2 is true.

Statement-1 is false, statement-2 is true.Because Hybridization of Au in above complex compound does not depend upon nature of ligand.
Although $C{l}^{-}$ is a weak ligand but due to high $z_{eff}$ values of $A{u}^{3+}$, unpaired electrons will pair up.
Hybridization : $ds{p}^2$; shape : square planar; ${\mu }_{eff}$ = 0
Hence option D is correct.
