Melting point of water is higher than petrol, because intermolecular forces in water are:
- A
Weaker than petrol
- B
Stronger than petrol
- C
Same as in petrol
- D
Negligible
Melting and boiling points depend on the intermolecular strengths of a molecule, higher the boiling and melting point stronger the intermolecular forces. Hence melting point of water is higher than petrol because water has stronger intermolecular forces than petrol.
Incorrect: Water has stronger hydrogen bonding, while petrol has weaker dispersion forces.
Melting and boiling points depend on the intermolecular strengths of a molecule, higher the boiling and melting point stronger the intermolecular forces. Hence melting point of water is higher than petrol because water has stronger intermolecular forces than petrol.
Incorrect: Intermolecular forces differ due to hydrogen bonding in water and dispersion forces in petrol.
Incorrect: Both substances have significant intermolecular forces affecting their melting points.
