Induced dipole intermolecular force is mainly responsible for the boiling point difference between cyclohexane and decalin. Correct answer: letter D.
The difference in boiling point between cyclohexane and decalin is due to the fact that decalin has a longer chain of carbon atoms and therefore has a larger surface area. This larger surface area allows for more intermolecular forces to be formed, specifically induced dipole forces.
<h3>How are these induced dipole forces created?</h3>
These dipole forces are created when the electrons of one molecule are attracted to the nucleus of another molecule, giving rise to a temporary dipole. This attraction between molecules is much stronger than the London dispersion forces that exist in cyclohexane, thus creating a higher boiling point in decalin.
Which intermolecular force do you think is primarily responsible for the difference in boiling point between cyclohexane and decalin?
A) Dipole-Dipole
B) Hydrogen bonding
C) Covalent
D) Induced Dipole
