Verified step by step guidance

1. Identify the structure of benzylamine, which consists of a benzene ring (C6H5) attached to a CH2 group, which is further attached to an NH2 group.
2. Understand that benzylamine hydrochloride is formed by the reaction of benzylamine with hydrochloric acid (HCl), resulting in the formation of an ammonium salt.
3. In the first structure, represent benzylamine hydrochloride as C6H5CH2NH3^+ Cl^-, where the NH2 group of benzylamine accepts a proton (H^+) from HCl, forming NH3^+.
4. In the second structure, depict the compound as C6H5CH2NH2·HCl, indicating that benzylamine is associated with HCl, forming a salt.
5. Name the compound as benzylammonium chloride, reflecting its identity as an ammonium salt formed from benzylamine and hydrochloric acid.

Key Concepts

Benzylamine Structure

Benzylamine is an organic compound consisting of a benzene ring attached to an amine group (-NH2). Its structure can be represented in two ways: the condensed structural formula, C6H5CH2NH2, and a more detailed Lewis structure showing the arrangement of atoms and bonds. Understanding its structure is crucial for recognizing its chemical properties and reactivity.

Hydrochloride Formation

Hydrochloride salts are formed when an amine reacts with hydrochloric acid, resulting in the protonation of the amine group. In the case of benzylamine, the resulting compound is benzylammonium chloride (C6H5CH2NH3Cl). This process is important in organic chemistry as it enhances the solubility of amines in water and is commonly used in pharmaceutical formulations.

Ammonium Salts

Ammonium salts are ionic compounds formed from the reaction of an amine with an acid, where the amine acts as a base. They typically consist of a positively charged ammonium ion (NH4+) and a negatively charged anion, such as chloride in the case of benzylammonium chloride. These salts are significant in various applications, including drug delivery and synthesis in organic chemistry.
