Question

The increase in boiling points of the noble gases from He to Xe is due to (A) decrease in ionization enthalpy (B) increase in polarization (C) increase in atomic volume (D) increase in electron gain enthalpy

Tardigrade Admin · Accepted Answer

As the polarisation increases with increasing size from He to Xe, induced dipole interactions i.e., van der Waals forces of attraction increases and hence the b.p. goes up.
