The boiling point of 1-butanol is 118C. The sum of the the hydrogen bonding plus the greater London dispersion forces gives 1-butanol the greater intermolecular forces and the higher boiling point. Just because London dispersion forces are said to be much weaker than the other van der Waals forces, don't sell them short.

The only intermolecular force that acts upon Diethyl Ether is Dispersion. This acts upon all molecules. It cannot have Hydrogen Bonding as a force acting upon it as no Hydrogen molecules bond with Nitrogen, Oxygen or Fluorine. It can also not have Dipole-Dipole as a force due to the fact that the molecule is not Polar.

It is followed by the ethanol, 1-propanol and 1-butanol. It is important to have the correct form of the propanol and butanol, as having the -OH group on a different carbon atom can slightly affect the intermolecular forces, and therefore the results of the lab. This lab addresses one Performance Expectation and three Science Practices. The stronger the intermolecular force is, the lower the solubility of CO 2 and the smaller the expansion coefficient. 25,26 The abovementioned results indicate that the molecular structure, intermolecular forces and microscopic dispersion state of the organic liquids are the key factors affecting the solubility of CO 2 and the corresponding ... ©H S. evain 2 Summarizing Intermolecular Forces From weakest to strongest Increasing ... 2-CH 3 T boil=308K 7. 2-butanol, CH 3-CHOH-CH 2-CH 3 T boil=372K (A) I only

It really just comes down to increased disperson and dipole-dipole forces. Take a look at 1-propanol. Now take a look at 2-propanol. They both have hydrogen bonding, dipole-dipole, and disperson forces. The catch is that 1-propanol has higher surface area leading to increased disperson forces in comparison to the latter molecule. 4. Using the diagram above, which alcohol has the strongest intermolecular forces? a. Methanol b. Ethanol c. 2-butanol d. 1-butanol e. 1-pentanol 5. Using the diagram above, explain why adding a solute to a pure solvent causes the vapor pressure to go down.
