Question

Quizplus · Accepted Answer

The functional group -NH₂ is an amine group, which acts as a base when placed in solution. This is because the lone pair of electrons on the nitrogen atom can accept a proton, thus increasing the concentration of hydroxide ions (OH-) in the solution and making it more basic. The other functional groups listed (-OH, -SH, -COOH, and -PO₄) can act as either acids or bases depending on the specific chemical environment in which they are placed.
