Final answer:
The compound 4-methylpentene is named following IUPAC nomenclature rules, resulting in the name 4-methyl-2-pentene, with the chain numbered to give the lowest numbers to the double bond and substituent.
Step-by-step explanation:
When naming organic compounds such as 4-methylpentene, the rules of the International Union of Pure and Applied Chemistry (IUPAC) nomenclature are applied.
The first step is to identify the longest chain containing the double bond, which determines the base name of the compound. In this case, it is a pentene chain. The following step is to number the chain in such a way that the double bond carbon atoms get the lowest possible numbers, resulting in the compound being named as 2-pentene.
With a methyl group positioned on the fourth carbon, the full name of the compound becomes 4-methyl-2-pentene. It is crucial to number the carbon atoms starting from the end nearest the first substituent encountered, which in this case is the methyl group.
Based on the information provided, other potentially discussed compounds include 3-methylhexane, trans-3-heptene, 4-methyl-1-hexene, 3,4-dimethyl-1-pentyne amongst others, although they're not central to this particular question.
