Question

In the reaction of aluminum bromide with ionized sodium bromide which compoiund is the lewis acid

Answer 1

Answer:

Aluminium bromide

Explanation:

Thinking process:

The aluminium bromide has the following structure:

$AlBr_{3}$

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:

$AlBr_{3} + Br^{-} = AlBr^{-} _{4}$

Thus, clearly the bromide ion is a base, and it donates electrons.

Answer 2

The answer is A) Aluminum Bromide
