The molecular formula and molar mass of two straight chain hydrocarbons are list

Question

The molecular formula and molar mass of two straight chain hydrocarbons are listed in the table above. Based on the information in the table, which compound has the higher boiling point, and why is that compound's boiling point higher? C_4H_10 because it has more hydrogen atoms, resulting in more hydrogen bonding C_4H_10 because it has more electrons resulting in greater polarizability and stronger dispersion forces C_2H_6 because its molecules are smaller and they can get closer to one another, resulting in stronger dispersion forces C_2H_6 because its molecules are more polar, resulting in stronger dipole-dipole attractions

Explanation / Answer

(b) C4H10 becuase it has more electrons resulting in greater polarisabilityand stronger dispersion forces.

And also as the molecular weight increases the velocities of their molecules will decrease resulting greater attractions among the molecules. ANd thus having more boiling point.
