The name of the organic compound CH3CH2OCH3 would be: Group of answer choices
a. Ethyl methanoate
b. Propenyl Propanone
c. Ethyl methyl
d. ether Propane.
The correct answer and explanation is :
The correct answer is c. Ethyl methyl ether.
Explanation:
The compound in question, CH3CH2OCH3, is an example of an ether. An ether is a type of organic compound that consists of an oxygen atom bonded to two alkyl or aryl groups. The general structure for ethers can be represented as R–O–R’, where R and R’ are alkyl or aryl groups. In this case, the two alkyl groups attached to the oxygen atom are ethyl (C2H5) and methyl (CH3).
To understand the name of this compound, we need to follow standard naming conventions for ethers:
- Identify the two alkyl groups: The compound has two groups attached to the oxygen atom:
- The first group is ethyl (CH3CH2), which is derived from ethane (C2H6).
- The second group is methyl (CH3), derived from methane (CH4).
- Name the groups alphabetically: In ethers, the name of the compound is constructed by naming the two alkyl groups attached to the oxygen, in alphabetical order, followed by the word “ether.” Therefore, the two groups are ethyl and methyl, and when listed alphabetically, it becomes “ethyl methyl ether.”
- Structure: The structure of this compound can be visualized as an oxygen atom (O) bonded to two carbon chains:
- The ethyl group (CH3CH2) is attached to the oxygen on one side.
- The methyl group (CH3) is attached to the oxygen on the other side.
- Why not the other options?
- a. Ethyl methanoate: This would be an ester, specifically ethyl formate (CH3CH2OCHO), not an ether.
- b. Propenyl Propanone: This name suggests an alkene and a ketone, which does not match the structure of the given compound.
- d. Ether Propane: While this mentions “ether,” the ordering is incorrect, and it should be “ethyl methyl ether.”
Therefore, ethyl methyl ether is the correct name for CH3CH2OCH3.
