Noble gases are named because of their inertness towards reactivity. Identify an incorrect statement about them.

Options

  1. ANoble gases are sparingly soluble in water.
  2. BNoble gases have very high melting and boiling points.
  3. CNoble gases have weak dispersion forces.
  4. DNoble gases have large positive values of electron gain enthalpy.

Correct answer

B. Noble gases have very high melting and boiling points.

Step-by-step solution

Due to the presence of weak dispersion forces, noble gases are sparingly soluble in water and they have low melting and boiling points. Due to the presence of completely filled electronic configuration they have large positive values of electron gain enthalpy.
