The reason for the noble gases to have low boiling and low melting point is

Options

A. atoms of the noble gases have weak covalent interaction
B. atoms of the noble gaes have weak dipole interaction
C. atooms of the noble gases have weak van der Waal's interaction
D. atom of the noble gaes have weak dispersion forces

Answer

C, D

Explanation

Nobel gases have low boiling point and low melting point because of
(i) waek van der Waal's interactions and,
(ii) weak dispersion forces.
Hence, option (c) and (d) both are the correct answer.
