## Question:

In the following reaction, identify the Lewis acid.

{eq}\displaystyle (a) CN^- \\ (b) H^+ \\ (c) Fe_3^+ \\ (d) OH^- {/eq}

## Lewis Model:

Acids and bases can be identified by using different models. One of the most common models is the Bronsted-Lowry definition. Another model that includes more substances is the lewis model. The lewis model is based on the acceptance and donation of an electron pair.
