Ether Composition and Properties

What substituent groups make up the following ethers?

1. Ethyl and phenyl

2. Propyl and benzyl

3. Ethyl and benzyl

4. Propyl and phenyl

5. None of these choices

Answer:

1. The substituent groups that make up ethyl phenyl ether are A. ethyl and phenyl.

2. The substituent groups that make up propyl benzyl ether are B. propyl and benzyl.

Ethers are a class of organic compounds that contain an oxygen atom bonded to two alkyl or aryl groups. Ethyl phenyl ether is formed when phenol is treated with ethyl iodide in the presence of a base like sodium hydroxide. This ether has a sweet, fruity odor and is commonly used as a solvent and flavoring agent in the food industry.

Propyl benzyl ether, on the other hand, is produced by the reaction of benzyl chloride with n-propyl alcohol. It serves as a solvent for resins, lacquers, and oils.

Among the given ethers, the substituent groups that make up ethyl phenyl ether are A. ethyl and phenyl, while the substituent groups in propyl benzyl ether are B. propyl and benzyl.
