Which of the following would be expected to have the lowest boiling point? CH3CH2CH2CH3, CH3CH2NHCH3, NH2CH2CH2NH2, CH3CH2CH2NH2

O CH3CH2NHCH3
O NH2CH2CH2NH2
O CH3CH2CH2NH2
O CH3CH2CH2CH3

CH3CH2CH2CH3

Explanation:

The boiling point of a compound depends on the nature of intermolecular interaction between the molecules of the compound.

If a molecule is nonpolar and has a low molecular mass, then its molecules are most likely held together only by weak intermolecular bonds such as dispersion forces. These forces are easily broken and the molecules move apart hence the molecule possess a low boiling point.

Polar molecules and molecules having higher molecular mass tend to have higher boiling points.

Among all the compounds listed, CH3CH2CH2CH3 is non polar and has the lowest molecular mass hence it exhibits the least boiling point.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
