Which of the following species is not stable?

1

[SiF6]2−[SiF_6]^{2-}

2

[GeCl6]2−[GeCl_6]^{2-}

3

[Sn(OH)6]2−[Sn(OH)_6]^{2-}

4

[SiCl6]2−[SiCl_6]^{2-}

Step-by-Step Solution

Due to the presence of d-orbital in Si, Ge and Sn they form species like [SiF6]2−[SiF_6]^{2-}, [GeCl6]2−[GeCl_6]^{2-}, [Sn(OH)6]2−[Sn(OH)_6]^{2-}. [SiCl6]2−[SiCl_6]^{2-} does not exist because six large chloride ions cannot be accommodated around Si4+Si^{4+} due to limitation of its size.
