The reaction that occurs between an amine and an acid is best illustrated by A)(CH₃)₂NH + HCl → (CH₃)₂NH ⁺Cl^-. B)(CH₃)₂NH + HCl → (CH₃)₂NH Cl^- + H₃O⁺. C)(CH₃)₂NH + HCl → (CH₃)₂NH₂⁺Cl^-. D)(CH₃)₂NH + HCl → (CH₃)₂NH₂⁺+ OH^-. E)(CH₃)₂NH + H₂O → (CH₃)₂N + H₃O⁺.

Question

Quizplus · Accepted Answer

The reaction between an amine and an acid is called an acid-base reaction. In this reaction, the amine (NH2) will act as a base and accept a proton (H+) from the acid (HCl) to form an ammonium ion (NH3+) and a chloride ion (Cl-). This is shown in choice C, where the amine (CH3NH2) reacts with HCl to form the ammonium ion (CH3NH3+) and the chloride ion (Cl-). In choice A and B, the products are incorrect and do not follow the correct acid-base reaction. Choice D and E are also incorrect as they do not involve an acid-base reaction between an amine and an acid.
