The intermolecular forces of alcohol are weaker than in water
Step 1 Understanding the concept:
A chemical bond between a hydrogen atom and an electronegative atom is defined as a hydrogen bond. Water molecules bonding together in the form of ice is an example of a hydrogen bond.
Hydrogen bonding is a strong bond, the more the hydrogen bond more will be an intermolecular force.
Step 2 Conclusion: Alcohols are polar covalent molecules with hydrogen bonding acting as the main intermolecular force. But their hydrogen bonding is weaker than that of water thus its melting and boiling points are lower than that of water.
Thus the intermolecular forces of alcohol are weaker than in water is a true statement.
