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.
question 10 (10 points)

Explanation:

Step1: Analyze intermolecular forces

Compounds with stronger intermolecular forces have higher boiling - points. The main types of intermolecular forces are hydrogen - bonding, dipole - dipole, and London dispersion forces.

Step2: Identify hydrogen - bonding compound

$CH_3(CH_2)_4CH_2OH$ is an alcohol and can form hydrogen bonds due to the presence of the $-OH$ group. Hydrogen bonds are stronger than dipole - dipole and London dispersion forces.

Step3: Analyze other compounds

$CH_3(CH_2)_2O(CH_2)_2CH_3$ is an ether and has dipole - dipole and London dispersion forces. $CH_3(CH_2)_5CH_3$ is an alkane and has only London dispersion forces. $CH_3CH_2CH = CHCH_2CH_3$ is an alkene and has only London dispersion forces (and a small dipole moment if it's a non - symmetrical alkene, but still weaker than hydrogen bonds).

Answer:

$CH_3(CH_2)_4CH_2OH$
