Select the substance that has the higher boiling point. select the substance that has the higher boiling point. a)c3h8 b)ch3oc)ch3

The question is incomplete. Here is the full version

Select the substance that has the higher boiling point. Select the substance that has the higher boiling point. a)C3H8 b)CH3OH c)CH3OCH3

b)CH3OH

Explanation:

a)C3H8 The dominant intemolecular force here are London dispersion forces.

             Dipole-dipole forces cancel out because the molecule is symmetric  

b)CH3OH  - The dominant intermolecular force is hydrogen bonding

c)CH3OCH3 - The dominant intemolecular force here are London

                       dispersion forces. Dipole-dipole forces cancel out because

                       the molecule is symmetric
