NEET · Chemistry · STD 12 - 5. Co-ordination chemistry
Which of the following species is not stable ?
- A \(\left[\mathrm{SiF}_{6}\right]^{2-}\)
- B \(\left[\mathrm{GeCl}_{6}\right]^{2-}\)
- C \(\left[\mathrm{Sn}(\mathrm{OH})_{6}\right]^{2-}\)
- D \(\left[\mathrm{SiCl}_{6}\right]^{2-}\)
Answer & Solution
Correct Answer
(D) \(\left[\mathrm{SiCl}_{6}\right]^{2-}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{SiCl}_{6}^{2-}\) does not exist since (i) size of \(\mathrm{Cl}^{-}\) is large so it cannot accommodate around \(\mathrm{Si}^{+4}\) due to limitation of slze
