Question

The correct IUPAC name of the following alkane is ___

Answer 1

Hint:The International Union of Pure and Applied Chemistry (IUPAC) nomenclature in organic chemistry is a way of naming organic chemical compounds that is prescribed in chemical nomenclature. It's in the Journal of Organic Chemistry's Nomenclature.

Complete answer:
The International Union of Pure and Applied Chemistry (IUPAC) nomenclature in organic chemistry is a way of naming organic chemical compounds that is prescribed in chemical nomenclature. It's in the Journal of Organic Chemistry's Nomenclature.
Rules for IUPAC
1. Identify the longest continuous carbon chain and give it a name.
2. Identify and name the various entities that are linked to this chain.
3. Begin numbering the chain from the end that is closest to a substituent group.
4. Assign an appropriate number and name to each substituent group's position.
5. Assemble the name by naming the classes alphabetically by full name (e.g. cyclopropyl before isobutyl).
When alphabetizing, the prefixes di, tri, tetra, and others, which are used to label many classes of the same kind, are ignored.
Now applying the rules,
The parent chain has 8 carbon atoms, with 2-ethyl groups at C3 and C6 and 1 methyl group at C2.
The parent chain which contains more branching is selected.
Hence, the correct IUPAC name is → 3,6-diethyl-2-methyloctane.
