Which of the following species is not stable?
- A[SiF
6
]
2− - B[GeCl
6
]
2− - C[Sn(OH)
6
]
2− - D[SiCl
6
]
2−
Solution & Step-by-step Explanation
[SiCl
6
]
2−
is not stable. This is due to:
Steric hindrance: The large size of six chloride ions cannot be easily accommodated around the relatively small Silicon atom.
The interaction between the lone pairs of chloride ions and the Silicon atom is weak compared to smaller fluorine ions ([SiF
6
]
2−
is stable).
