Identify the IUPAC name for CH3NH2.Select answer from the options belowethylaminemethanamineethanaminepropanaminepropylaminemethylamine

Break Down the Problem

1. Identify the molecular formula given: CH₃NH₂.
2. Analyze the structure of the molecule to determine the longest carbon chain and functional groups.

Relevant Concepts

• The IUPAC naming rules state that the longest carbon chain is identified first, and then the functional groups are used to form the name.
• NH₂ (amino group) makes the compound an amine.
• A carbon atom with three hydrogens (CH₃) indicates a methyl group.

Analysis and Detail

1. The molecule has a single carbon (C) atom which is bonded to three hydrogen (H) atoms (this represents a methyl group, CH₃).
2. The nitrogen (N) is attached to this carbon atom and has two hydrogen atoms attached (NH₂), making it an amine since it contains the amino group.
3. The longest carbon chain contains only one carbon, and with the amino group, the correct name follows the amine nomenclature.

Verify and Summarize

• The longest carbon chain has 1 carbon atom.
• The amino group attached results in the name being based on the parent structure, which is methane (1 carbon).
• Adding the amine suffix to the parent name, we get methanamine.

Final Answer

The IUPAC name for CH₃NH₂ is methanamine.
