The correct answer is isobutane, a four membered, branched hydrocarbon. When discussing boiling points of hydrocarbons, it is important to remember that branching decreases a molecule's boiling point.
We can first eliminate hexane and pentane as our answers, as neither are branched. From here, we can come upon 2,3-dimethylbutane as our answer because it is more branched than 2-methylpentane. Also important when ranking hydrocarbons in terms of boiling point is the number of carbons - more carbons means a higher boiling point.

Hanley Rd, Suite St. Louis, MO We are open Saturday and Sunday! Subject optional. Email address: Your name:. R hydroxypentanoic acid. Explanation : Boiling point is highly dependent on the intermolecular forces of a compound. Report an Error. Possible Answers: The triple bond of an alkyne consists of three pi-bonds. Terminal alkynes are less acidic than internal alkynes. Internal alkynes are more stable than terminal alkynes. Terminal alkynes are stronger compounds than internal alkynes.
Correct answer: Internal alkynes are more stable than terminal alkynes. Explanation : The answer is "Internal alkynes are more stable than terminal alkynes" as it is the only true statement in regards to alkynes. Which of the following compounds will be the most volatile have the lowest boiling point?
Possible Answers: III. Correct answer: III. Explanation : When comparing relative volatilities of compounds, you must consider the molecular weight of a compound, as well as the intermolecular attractive forces between the identical molecules found in a sample of the compound in question.
