(a)
Interpretation:
The given statement, following questions has to be explained.
Concept Introduction:
Intermolecular forces are Van der Waals forces. They are weak and have three types viz., London dispersion forces, dipole-dipole forces and hydrogen bonding. Hydrogen bonding is relatively the strongest one.
- Intermolecular forces are the forces acting between molecules whereas Intramolecular forces are the forces that operate within a molecule.
- Hydrogen bonding is a special type of Dipole-dipole forces but stronger than the former.
- London dispersion forces exist in non-polar covalent compounds whereas dipole-dipole forces exist in polar covalent compounds but both are weak.
- Larger the molecular size, stronger the London dispersion force.
- Arrangement of major types of intermolecular forces in increasing order of strength:
There exist no deviations in this arrangement.
(b)
Interpretation:
The given statement, following questions has to be explained.
The substance has smaller heat of fusion has to be identified.
