Question

which compound has the highest boiling point?
ch3(ch2)4ch2oh
ch3(ch2)2o(ch2)2ch3
ch3(ch2)5ch3
ch3ch2ch=chch2ch3
all of the compounds have the same boiling point.

Explanation:

Step1: Analyze intermolecular forces

Boiling - point is related to intermolecular forces. Hydrogen - bonding is the strongest among common intermolecular forces in these compounds.

Step2: Identify compound with hydrogen - bonding

$CH_3(CH_2)_4CH_2OH$ has a hydroxyl group ($-OH$), which can form hydrogen - bonds. The other compounds do not have functional groups that can form hydrogen - bonds. Compounds with stronger intermolecular forces have higher boiling points.

Answer:

$CH_3(CH_2)_4CH_2OH$
