Identify the structure of propylamine, which is a primary amine with the formula C3H7NH2. It consists of a propyl group (C3H7) attached to an amino group (NH2).
Understand that the propylammonium ion is formed when the nitrogen atom in propylamine gains an additional hydrogen ion (H+), resulting in a positively charged nitrogen atom.
Visualize the structure: the propyl group remains unchanged, while the nitrogen atom now has four bonds—three to hydrogen atoms and one to the propyl group. This results in a positively charged nitrogen atom, denoted as N+.
Draw the structure: Start with the propyl chain, which is a straight chain of three carbon atoms. Attach the nitrogen atom to the end of the chain, and then add three hydrogen atoms bonded to the nitrogen.
Ensure the nitrogen atom carries a positive charge, indicated by a plus sign next to the nitrogen (N+), to represent the propylammonium ion.
