Question
**Title: Understanding IUPAC Nomenclature with Skeletal Structures** **Objective: Learn to provide the correct IUPAC name for skeletal (line-bond) structures.** --- **Task: Identify the IUPAC name for the given skeletal structure.** *Description of Structure:* The image showcases a skeletal structure common in organic chemistry. The line-bond structure consists of a main chain with three carbon atoms. Each vertex and endpoint in the structure represents a carbon atom, in line with the conventions of skeletal structures where hydrogen atoms are not depicted explicitly. **Analysis:** 1. **Main Carbon Chain**: - The longest continuous chain consists of three carbon atoms, indicating propane as the base name. However, observe carefully, the longest chain could potentially be extended if considering branches. 2. **Substituents**: - Two methyl groups are attached to the middle carbon (second position). - Another methyl group is attached to the third carbon in the longest chain. **Correct IUPAC Name:** - The compound is named 2,3,3-trimethylpentane due to: - The longest carbon chain actually being five carbons long ("pentane"). - Three methyl groups attached at the 2nd and 4th positions of the longest chain. This name corrects the initial suggestion given as "2,4-tetrapentane," which is not a valid name under IUPAC standards, as "tetra" refers to a quadruple substitution that doesn't match the structure presented. *Remember*, accurately identifying the longest carbon chain and correctly numbering it to provide the smallest possible numbers for substituents is essential in determining the correct IUPAC name. --- This exercise illustrates the importance of applying systematic IUPAC naming rules to effectively communicate molecular structures in chemistry.
