Question

The correct IUPAC name of the structure is:

• A. 3-isopropyl-5,5-dimethyl heptane
• B. 5-Ethyl-3,3,6-trimethyl heptane
• C. 3,3-Dimethyl-5-isopropyl heptane
• D. 3-Ethyl-2,5,5-trimethyl heptane

Answer 1

The correct option is D 3-Ethyl-2,5,5-trimethyl heptane

The correct IUPAC name of the structure is 3-ethyl-2,5,5-trimethyl heptane.
The parent hydrocarbon contains 7 carbon atoms and is called heptane. one ethyl group and 3 methyl groups are present as substituents.
The carbon atoms are numbered from that end which is nearest to the point of branching. The parent chain contains maximum number of substituents.
