What is the structure of methyl amine?

• A. CH₃-NH₂
• B. CH₃-CH₂-NH₂
• C. CH₃-C=O-NH₂
• D. CH₃-C-NH₂

Answer: (A)

Methyl amine is represented by the structure CH₃-NH₂. This compound consists of a methyl group (CH₃) attached to an amine group (NH₂). The methyl group's presence indicates that there are three hydrogen atoms attached to a carbon atom, which is further connected to the nitrogen atom of the amine. This simple structure highlights that methyl amine is the simplest form of aliphatic amines, where a carbon atom is directly bonded to the nitrogen atom. The other structures provided in the options depict different compounds. For example, the second option shows an ethyl group (CH₃-CH₂) connected to an amine group, which would correctly represent ethyl amine, rather than methyl amine. The third option includes a carbonyl group (C=O) bonded to the amine, indicating it is an amide rather than an amine. The fourth option presents a structure that implies a branching or more complex framework that is not characteristic of methyl amine. Therefore, the selection of CH₃-NH₂ accurately identifies the structure of methyl amine.
