Discover the Common Name for the Ether
What is the common name for a compound with an oxygen bonded to a 5-carbon ring and an ethyl group?
A. Cyclopentyl ethyl ether
B. Cyclopentoxyethane ethoxy
C. Cyclopentane ethyloxy
D. Cyclopentane
Answer:
The common name for the compound described, where an oxygen is bonded to a 5-carbon ring and an ethyl group, is A. cyclopentyl ethyl ether.
The compound described consists of a five-carbon ring, known as cyclopentane, with an oxygen atom bonded to it. Additionally, there is an ethyl group attached to the oxygen atom.
When naming ethers, the common naming system typically involves identifying the alkyl groups attached to the oxygen atom. In this case, the alkyl group is ethyl, which consists of two carbon atoms bonded together.
To name the compound, we start by combining the names of the two alkyl groups in alphabetical order. In this case, we have "ethyl" as the first part of the name.
The second part of the name describes the carbon ring structure. Since we have a five-carbon ring, we use the prefix "cyclopent" to indicate a five-membered carbon ring.
Finally, we add the word "ether" to indicate the presence of an oxygen atom bonded to two alkyl groups.
Putting it all together, the common name for the compound is "cyclopentyl ethyl ether."
