Question

question 30 (1 point) listen which compound has the lowest boiling point? ch3(ch2)4ch2oh ch3(ch2)4ch3 ch3o(ch2)4ch3 ch3(ch2)4ch2oh and ch3o(ch2)4ch3 have the same boiling point and boiling point is lower than that of ch3(ch2)4ch3.

Explanation:

Step1: Analyze intermolecular forces

Boiling - point is related to intermolecular forces. $CH_3(CH_2)_4CH_2OH$ has hydrogen - bonding due to the $-OH$ group, which leads to higher boiling - point.

Step2: Compare non - polar and polar compounds

$CH_3(CH_2)_4CH_3$ is a non - polar alkane with only London dispersion forces. $CH_3O(CH_2)_4CH_3$ is an ether, which is polar and has dipole - dipole forces in addition to London dispersion forces. Since London dispersion forces are generally weaker than dipole - dipole forces (for compounds of similar molar mass), the non - polar $CH_3(CH_2)_4CH_3$ has the weakest intermolecular forces among them.

Answer:

$CH_3(CH_2)_4CH_3$
