Q. What is the dominant intermolecular force or bond that must be overcome in converting liquid CH₃OH to a gas?
A) Dipole-dipole interaction
B) Covalent bonds
C) London dispersion force
D) Hydrogen bonding
Explanation
[Solution from source] Methanol molecules are linked by O–H···O hydrogen bonds, which are the dominant forces to be overcome on boiling. Covalent bonds are broken only in a chemical change, and dipole–dipole and London forces are present but weaker. Answer (4).
