All the elements of group 14 form tetranaldes of general formula `MX_(4)` which are compounds (except `SnF_(4)` and `PbF_(4)`) and have tetrahedral structure. The stability of these tetrahaldes dec reases as we move from C to Pb. The of `MX_(2)` increases as we move from C to Pb. Tetrahaldes are convalent compounds while dhalides are ionic.
Which of the following does not exist?

A

`C Cl_(4)`

B

`SiF_(40`

C

`PbBr_(4)`

D

`SnCl_(4)`

Text Solution

Verified by Experts

`PbBr_(4)` does not exist, intact, Br ions reduce `Pb^(4+)` ions to `Pb^(2+)` which are more stable according to inert pair effect also.

Atoms of eight elements A, B, C, D, E, F, G and H have the same number of electronic shells but are different in their outermost shells. It was found that elements A and G combine to form an ionic compound which can also be extracted from sea water. Oxides of the elements A and B are basic in nature while those of E and F are acidic. The oxide of elements D is almost neutral. Which one of the following will have largest atomic radii?
