## Question:

Which of the following is a Lewis acid?

a. {eq}CH_4 {/eq}

b. {eq}BCl_3 {/eq}

c. {eq}CHCl_3 {/eq}

d. {eq}NH_3 {/eq}

e. None of the above are Lewis acids

## Acids and Bases:

The Bronsted-Lowry and Lewis definitions for acids and bases noted that there were some species that behaved as acid or bases but did not produce hydrogen and hydroxide ions upon dissolution, as Arrhenius had defined acids and bases, respectively.
