Question

$A{g}^{+}$ forms many complexes, some of these are $\left[Ag\right(N{H}_3{)}_2{]}^{+},Ag(CN{)}_2{]}^{-},[Ag(S_2{O}_3{)}_2{]}^{3-}$. Which of the following statements is true ?

• A. In these complexes, $A{g}^{+}$ is Lewis base
• B. The hybridization of $A{g}^{+}$ is $s{p}^2$.
• C. The $A{g}^{+}$ complexes are good reducing agents
• D. These complexes are all linear

Answer 1

Answer: (D)

These complexes are all linear

$\left[Ag\right(N{H}_3{)}_2{]}^{+},Ag(CN{)}_2{]}^{-},[Ag(S_2{O}_3{)}_2{]}^{3-}$
+1 +1 +1
In these complexes, $A{g}^{+}$ is Lewis acid.
The hybridization of $A{g}^{+}$ is $sp$.
