Question

Which of the following compounds contains an ether functional group? O CH3 - CH2 -0 - CH2 - CH3 СН3 O CH3-C-O-H CH3 O CH3-C-H OCH-O-H o CH3-CH2-C-CH3

Answer 1

Ethers are compounds that contain the functional group -O-. The compound CH3-O-CH2-CH2-CH3 is methyl propyl ether.

Step-by-step explanation:

Ethers are compounds that contain the functional group -O-. In the IUPAC system, the oxygen atom and the smaller carbon branch are named as an alkoxy substituent and the remainder of the molecule as the base chain, as in alkanes. The compound CH3-O-CH2-CH2-CH3 is methyl propyl ether.

Answer 2

The compound CH3-CH2-O-CH2-CH3 contains the ether functional group and can be named ethylmethyl ether or methoxyethane.

Step-by-step explanation:

The student has asked which of the listed compounds contains an ether functional group. An ether is characterized by an -O- linkage where two carbon chains are connected through an oxygen atom. Based on the structures provided, the compound CH3-CH2-O-CH2-CH3 represents an ether because it has the general structure of R-O-R', with 'R' and 'R'' being alkyl groups. This compound would commonly be named ethylmethyl ether in the common name system, or methoxyethane in the IUPAC system.
