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 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 but (R) is not the correct explanation of (A)

Answer

D

Explanation

Noble gases have very low boiling points due to weak dispersion forces. Their general electronic configuration is `ns^(2)np^(6)` (except He).
