Identify the species, which does not exist?
- A \(\left[\mathrm{SiF}_6\right]^{2-}\)
- B \(\left[\mathrm{SiCl}_6\right]^{2-}\)
- C \(\left[\mathrm{GeCl}_6\right]^{2-}\)
- D \(\left[\mathrm{Sn}(\mathrm{OH})_6\right]^{2-}\)
Answer & Solution
Correct Answer
(B) \(\left[\mathrm{SiCl}_6\right]^{2-}\)
Step-by-step Solution
Detailed explanation
Presence of vacant \(d\)-orbitals in \(\mathrm{Si}, \mathrm{Ge}\) and \(\mathrm{Sn}\), makes the existence of species \(\left[\mathrm{SiF}_6\right]^{2-},\left[\mathrm{GeCl}_6\right]^{2-}\) and \(\left[\mathrm{Sn}(\mathrm{OH})_6\right]^{2-}\) feasible. But…
