A strongly alkaline solution of a monoaminodicarboxylic acid contains how many basic groups ?

Answer

3

Explanation

In strongly alkaline solution of an amino acid, all of its —COOH groups are converted into —`COO^(-)`. Thus a strongly alkaline solution of a monoaminodicarboxylic acid will have one —`NH_2` and two —`COO^(-)` groups, all of which are basic in nature. Further, —`NH_(2)` is more basic than a -COO group.
