Functional group that acts like a base?

What functional group acts as base?





a. sulfhydryl


b. amino


c. carboxyl


d. carbonyl


e. none of these|||B. amino groups consist of -NH2. The lone pair is able to accept a proton (H+) from solution, thus removing hydrogen ions from solution. Based on the definition of a base (e.g. a base is a molecule that removes hydrogen ions from solution), amino groups would be the best answer.
