Assertion (A): Noble gases have very low boiling points.
Reason (R): All noble gases have general electronic configuration of `ns^(2)np^(6)` (except He).

Options

A. Both (A) and `(R)` are true and `(R)` is the correct explanation of (A)
B. (A) is false but `(R)` is true
C. (A) is true but `(R)` is false
D. Both (A) and `(R)` are true and `(R)` is the not the correct explantion of (A)

Answer

D

Explanation

Boiling points of noble gases are quite low as compared to other elements of comparable atomic masses due to weak van der Waals. forces of attraction which hold the atoms together in the liquid and in the solid states.
