Question

Explain the rules for naming mono or polyfunctional compounds.

✓

Answer

Identification of parent chain: The longest carbon chain containing the single or the principal functional group is identified as parent chain.
e.g. Ethers are named as alkoxyalkane. While naming it, the larger alkyl group is chosen as parent chain.
Numbering of parent chain: It is done so as to give the lowest possible locant numbers to the carbon atom of this functional group.
Suffix: The name of the parent hydrocarbon is modified adequately with appropriate suffix in accordance with the single/principal functional group.
Names of the other functional groups (if any) are attached to this modified name as prefixes. The locant numbers of all the functional groups are indicated before the corresponding suffix/prefix.
