Transcribed Image Text:### Question 16: Chemical Nomenclature
**What is the IUPAC name of the following compound?**
The question is accompanied by a diagram of the chemical structure, featuring a cyclopentane ring attached to a nitrogen atom, with an ethyl group and a methyl group also bonded to the nitrogen.
**Options:**
1. \( N \)-ethyl-\( N \)-methylcyclopentanamine
2. \( N \)-cyclopentyl-\( N \)-methylethanamine
3. \( N \)-ethyl-\( N \)-methylpentanamine
4. \( N \)-methyl-\( N \)-ethylcyclopentylamine
**Explanation of Diagram:**
The diagram depicts a nitrogen atom (N) bonded to three different groups:
- A cyclopentane ring.
- An ethyl group (CH₂CH₃).
- A methyl group (CH₃).
**Explanation:**
Nomenclature for this compound involves identifying the longest chain attached to the nitrogen and naming the substituents in alphabetical order with appropriate N-prefixes to indicate their attachment to the nitrogen atom.
The correct IUPAC name identifies:
- The presence of the cyclopentane ring as the primary structure.
- An ethyl group and a methyl group both bonded to the nitrogen atom.
Therefore, based on IUPAC naming conventions, the correct name is:
**\( N \)-ethyl-\( N \)-methylcyclopentanamine**
