The Normal Boiling Point for H₂Se is Higher Than the Normal

Multiple Choice

The normal boiling point for H₂Se is higher than the normal boiling point for H₂S. This can be explained by

A) larger dipole-dipole forces for H₂Se .
B) larger dispersion forces for H₂Se .
C) larger hydrogen-bond forces for H₂Se .
D) larger dipole-dipole forces, larger dispersion forces, and larger hydrogen-bond forces for H₂Se .
