The dominant intermolecular force that must be overcome to convert liquid methanol to its vapour is

Options

  1. Acovalent bonds
  2. Bdipole-dipole interactions
  3. Chydrogen bonds
  4. Dcoordinate bonds

Correct answer

C. hydrogen bonds

Step-by-step solution

In methanol ( CH ₃ OH ) , intermolecular hydrogen bonding exists. When H -atom is directly linked with nitrogen, oxygen or fluorine, it forms inter or intramolecular H-bond. Hence, the intermolecular H -bonding in methanol molecule must be overcome in converting liquid CH ₃ OH to vapour.
