Which of the following, heterocyclic amine and/or secondary amine, best describes the molecule shown below?

amine molecule

  1. Heterocyclic amine only
  2. Secondary amine only
  3. Both heterocyclic amine and secondary amine
  4. Neither heterocyclic amine nor secondary amine

 

Explanation

 

Secondary amines follow the chemical formula R-NH-R’; heterocyclic amines include cyclic ring structures with nitrogen incorporated into ring. In the molecule shown above, nitrogen is situated within the ring structure making this a heterocyclic amine. R-NH2 is the other nitrogen containing substituent within the molecule shown above. Since only one R-group is attached, this is considered a primary amine instead of a secondary amine. Therefore, A is the correct answer.
