Question: Give the IUPAC name for the following hydrocarbon, and convert the drawing into a skeletal structure.

Step-by-Step Solution

Answer

Answer

The IUPAC name for above compound is 3, 3, 4, 5-Tetramethylheptane.

Step 1: IUPAC nomenclature

The parent chain is given higher priority while providing a name to a particular compound. Substituents with greater priority are named prior to those with lesser priority.

Step 2: Providing IUPAC nomenclature and skeletal structure of the given molecule

The given compound has seven carbon atoms in the parent chain and is called  heptane. The third position comprises of two methyl groups as the substituent. The fourth and fifth position has one methyl group as the substituent. Hence, the name of the compound is 3,3,4,5-Tetramethylheptane.

The structure is shown below.
