Question

What is the strongest intermolecular force present in liquid ethanol?
Options
A induced dipole-induced dipole
B dipole-dipole, specifically hydrogen bonding
Correct Answer
C dipole-dipole, but not hydrogen bonding
D ion-dipole
Correct Answer

Option B is the correct answer.

Detailed Explanation

Ethanol molecules can form hydrogen bonds (a strong type of dipole-dipole interaction) between the O-H hydrogen of one molecule and the oxygen of another. This is the strongest intermolecular force in liquid ethanol.

Hint

What strong intermolecular force involves O-H bonds?
