Final answer:
The IUPAC name for the given compound is 4-Methyl-5-propyloctane. Other isomers include 3-methylhexane and 3,4-dimethyl-1-pentyne. The alkyne isomers of C4H6 are 1-ethyl-2,3-dimethylcyclopropane and 1-ethyl-2,4,5-trimethylcycloheptane.
Step-by-step explanation:
The IUPAC name for the given compound is 4-Methyl-5-propyloctane. This name indicates that there is a methyl group attached to the fourth carbon atom and a propyl group attached to the fifth carbon atom of the octane chain.
Other isomers that contain a five-carbon chain with three methyl substituents include:
- 3-methylhexane
- 3,4-dimethyl-1-pentyne
Lewis structures and IUPAC names for the alkyne isomers of C4H6 are:
- 1-ethyl-2,3-dimethylcyclopropane
- 1-ethyl-2,4,5-trimethylcycloheptane
