Understanding the Structure
The compound CH3-O-C2H5 consists of two hydrocarbon chains connected by an oxygen atom. The structure can be broken down as follows:
- CH3 represents a methyl group (–CH3).
- O is the oxygen atom that connects the two groups.
- C2H5 represents an ethyl group (–C2H5).
IUPAC Naming Convention
In IUPAC nomenclature, the names of ethers follow a specific convention. Ethers are named by identifying the two alkyl groups attached to the oxygen atom, with the suffix "ether" added to the name.
Identifying Alkyl Groups
- The two alkyl groups in this compound are:
- Methyl (from CH3)
- Ethyl (from C2H5)
When naming ethers, the shorter alkyl group is typically mentioned first, followed by the longer one.
Correct Name
According to the IUPAC rules for naming ethers:
- The methyl group is listed first because it is the smaller alkyl group.
- The ethyl group is listed second.
- The correct name becomes "Methoxy" for the methyl group and "Ethane" for the ethyl group.
Putting it all together results in the name "Methoxy ethane."
Conclusion
Thus, the IUPAC name of CH3-O-C2H5 is indeed:
- Methoxy ethane (Option C)
This name accurately reflects the structure and follows the IUPAC naming rules for ethers.
