Answer:

[tex]Br_{4}Si[/tex] is written incorrectly

Explanation:

In a molecular formula, the central atom in it's lewis structure is written first followed by other bonded atoms.

The least electronegative atom (except H) is the central atom in a lewis structure.

In [tex]Br_{4}Si[/tex], Si is the least electronegative atom as Br has higher electronegativity than Si. Therefore Si is the central atom in lewis structure of [tex]Br_{4}Si[/tex]. So molecular formula of [tex]Br_{4}Si[/tex] should be written as [tex]SiBr_{4}[/tex].

In all other cases, the least electronegative atom have been written first.

So, [tex]Br_{4}Si[/tex] is written incorrectly.
