3. Consider the three isomeric alkanes n-hexane, 2,3-dimethylbutane, and 2-methylpentane. Which of the following correctly lists these compounds in order of increasing boiling point? 2-methylpentane < 2,3-dimethylbutane < n-hexane 2-methylpentane < n-hexane < 2,3-dimethylbutane 2,3-dimethylbutane < 2-methylpentane < n-hexane -hexane < 2-methylpentane < 2,3-dimethylbutane n-hexane 2,3-dimethylbutane < 2-methylpentane
Isomers are hydrocarbon compounds that have the same molecular formula but have different structures. The order of boiling points among the isomeric compounds is 2,3-dimethylbutane < 2-methylpentane < n-hexane.
Detail Explanation
Every hydrocarbon compound has several isomers. Isomers occur when the same compound is found but the hydrocarbon structure is different. The boiling point of a hydrocarbon is determined by how much of the carbon, branched or straight chain, has hydrogen bonds or not.
For hydrocarbon compounds that are mutually isomers, it can be ascertained that the number of carbons is the same, so we can determine the boiling point of the straight or branched chain only.
The boiling point of hydrocarbon compounds that have straight chains will be higher than those of hydrocarbons that have alkyl branches.
So in this question, the order of boiling points between isomeric compounds can be obtained as follows.
2,3-dimethylbutane < 2-methylpentane < n-hexane.

[tex]\large \bold {SOLUTION}[/tex]
See picture above for the structure.
A compound that is given has always an option to provide its new IUPAC name.
For instance, 2-isobutylhexane can be renamed into another IUPAC name, this is what you called a resonance structure.
The structure in dark blue is the isobutyl group bonded in the hexane group. By rearranging the carbons, we can start at the root of the isopropyl compound and it provides 2 bonded methyl groups in carbons 2 and 4
Under these conditions, the resonance structure of 2-isobutylhexane is e.) 2,4-dimethyloctane

28. Examine this cycloalkene. Its correct name is 3-ethyl-1-methylcyclopentane. Why is it not named as 1-methyl-3-ethylcyclopentene and 5-ethyl-2-methylcyclopentene? Why are these names incorrect?
Answer:
I am confused by your question. is the compound's correct name is really a cycloalkane? But in your given direction, it is told to examine the cycloalkene.
but anyways, if the coimpound is really a cyclopentene, then
- it will not be named as 1-methyl-3-ethylcyclopentene since according to the nomenclature of cycloalkenes you have to arrange the name in alphabetical order using the full name, you must include the prefixes like di-, tri-. so in this case, ethyl shoud go first instead of methyl.
next, why not 5-ethyl-2-methylcyclopentene, even if is an alphabetocal order, again, according to IUPAC rules. you will have to name the chain starting with the nearest or smallest number of substituents. Examining the correct cycloalkene, you will observed that there is only 1 carbon in between the carbons with substituents,, we have Carbon 1, Carbon 2 and Carbon 3 .
but if you will try to look at the structure of 5-ethyl-2-methylcyclopentene, you will notice that there is 4 carbon difference between the substituents,
