The correct answer and explanation is:
The structure provided, CH₃CH=CH₂OCH₃, represents a compound with the name methoxypropene or methoxypropene-1. Let’s break it down to understand the common name and its reasoning.
Correct Answer:
Methoxypropene (commonly referred to as methyl vinyl ether when focused on similar structures).
Explanation:
- Structure Analysis:
- CH₃CH=CH₂: This indicates a propene backbone, where one double bond exists between the second and third carbon atoms. The prefix “prop” refers to three carbons, and “ene” indicates the presence of a double bond.
- OCH₃: This is a methoxy group (-OCH₃), meaning a methyl group is attached to oxygen.
- Nomenclature:
- Start by identifying the longest carbon chain containing the double bond: propene.
- The methoxy group (-OCH₃) is attached to the double-bonded carbon chain. Depending on where it’s placed, it affects the numbering. In this case, the methoxy group is on the first carbon of the double bond.
- The position of the double bond is automatically implied by the simplest placement of substituents.
- Common Naming:
- The compound is commonly known as methoxypropene, derived by combining the functional groups.
- While systematic names might vary (like methyl vinyl ether), these names are widely used interchangeably.
- Applications:
- This compound is used in polymerization reactions to form resins and coatings.
- Its double bond enables it to act as a monomer in synthetic processes.
By understanding the rules of IUPAC naming and common naming conventions, identifying functional groups and naming compounds systematically becomes much easier.
