The bigger molecule has more interactions and hence the higher b.p. CH3CH2OCH2CH3 is a bigger molecule than CH4 and CH3CH3, so has more dispersion forces. It also has dipole-dipole forces due to the polarised C-O bonds. CH3OH and CH3CH2OH have hydrogen bonds due to the very electronegative O atom bonded to the H atom

Answer:

The correct answer t is ;CH_4 has a lower mass compared to CH-3CH-3 which leads to a higher boiling point.

Explanation:

Boiling point of alkanes increases with increase number of carbon atoms in the chain.

This is because along with increase in carbon atom molar mass of alkane also increases by which surface area of molecule increases which further results in increase in weak vander wall forces among the molecule. Due to this molecules associates strongly with each other and boils at high temperature
