What is the IUPAC name of this structure?
Correct answer: D. 3-Ethyl,2,3-Dimethylhexane
- A. 3-Ethyl 2-methyl hexane
- B. Iso propyl hexane
- C. 4-Ethyl 5-methyl hexane
- D. 3-Ethyl,2,3-Dimethylhexane
Explanation
If we start counting from immediate right end of the chain then, there are two methyl groups on carbon 2 and 3, also a ethyl group on carbon 3. The total number of carbon atoms in the parent chain (longest chain) is 6. Hence, the IUPAC name would be 3-Ethyl,2,3-Dimethylhexane.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
