Question

Which of the following statement is not correct in the naming of ethers according to IUPAC rules?

• A. Ethers are named as alkoxy alkanes
• B. The numbering of the parent chain is done in such a way so that the carbon atom linked to the -O-atom gets the lowest number.
• C. The two alkyl groups attached to the oxygen are put in alphabetical order
• D. In the case of simple ethers, the prefix tri is attached before the name of the alkyl group.

Answer 1

The correct option is D In the case of simple ethers, the prefix tri is attached before the name of the alkyl group.

If both the alkyl groups attached to the $-O-$ atoms are same, then the prefix 'di' is added before the alkyl group.

Example: $C{H}_3-O-C{H}_3$ is named as dimethyl ether.
