Solution: Which of the following is a Lewis acid?A) BBr3B) CCl4C) NH3D) CHBr3E) None of the above are Lewis acids.

Problem

Which of the following is a Lewis acid?

A) BBr3

B) CCl4

C) NH3

D) CHBr3

E) None of the above are Lewis acids.

Solution

We’re being asked which of the given compounds is a Lewis acid

Let’s first define a Lewis acid and a Lewis base.


Based on the Lewis definition:

Lewis acid is an electron pair acceptor.

Some characteristics of a Lewis acid:

When hydrogen is connected to an electronegative element such as P, O, N, S or halogens

▪ hydrogen gains a partially positive charge → makes hydrogen act as a Lewis acid

Positively charged metal ions
