Answer:
Option (4) is correct
Explanation:
- NaCl is an ionic solid.
and
ions are held together by strong coloumbic attractive force. Hence NaCl has highest boiling point'
- Ar is a monoatomic molecule. Hence only weak london dispersion force exists between Ar atom/molecules. Hence it requires lowest amount of energy to boil and thereby possess lowest boiling point.
and
are polar protic molecules. Hence they possess london dispersion force, dipole-dipole force and hydrogen bonding as intermolecular forces.
- Dipole-dipole force is stronger in
Hence order of boiling point :
