Boiling Point Comparison

Postby AChoudhry_1L » Thu Nov 21, 2019 7:53 pm

Which would have a higher boiling point between C2H5OC2H5 (diethyl ether) and C4H9OH (butanol) and why is this? This is from homework problem 3F 5.

Butanol would have a higher boiling point. This is because when you draw out the Lewis structures, you see that diethyl ether has London dispersion forces and dipole-dipole interactions. Butanol, on the other hand, has London dispersion forces and hydrogen bonding due to the O-H. Since hydrogen bonds are the stronger intermolecular force, it would take more energy to boil a sample of butanol.

Return to “Interionic and Intermolecular Forces (Ion-Ion, Ion-Dipole, Dipole-Dipole, Dipole-Induced Dipole, Dispersion/Induced Dipole-Induced Dipole/London Forces, Hydrogen Bonding)”
