JEE Main Chemistry question

Dipole-dipole attractive forces are strongest between the molecules of

(A)He
(B)
(C)
(D)Correct

Answer: (D)

Solution

Dipole-dipole attractive forces can only exist between molecules that possess a permanent dipole moment. He (a noble gas atom), (symmetric tetrahedral, non-polar) and (linear, symmetric, non-polar) all have zero dipole moment, so they experience no
