Answer:
Aluminium bromide
Explanation:
Thinking process:
The aluminium bromide has the following structure:
[tex]AlBr_{3}[/tex]
The compound is a Lewis acid.
Aluminium bromide has a vacant p-orbital so it accepts a lone pair of electrons and acts as a Lewis acid.
Sodium bromide, on the other hand, donates electrons and acts as a Lewis base like this:
[tex]AlBr_{3} + Br^{-} = AlBr^{-} _{4}[/tex]
Thus, clearly the bromide ion is a base, and it donates electrons.
