Step 1: Understand what an ether is. An ether is a type of organic compound that contains an oxygen atom connected to two carbon-containing groups (alkyl or aryl groups).
Step 2: Identify the structure of dimethyl ether. Dimethyl ether has the formula CH3-O-CH3, where the oxygen atom is connected to two methyl groups (CH3).
Step 3: Confirm that dimethyl ether fits the definition of an ether. Since it has an oxygen atom connected to two carbon groups, it is indeed an ether.
Step 4: Compare dimethyl ether with other compounds if provided. Check if any other options have a similar structure with an oxygen atom connected to two carbon groups.
