The normal boiling point for HBr is higher than the normal boiling point for HCl.This can be explained by A)larger dipole-dipole forces for HBr. B)larger dispersion forces for HBr. C)larger hydrogen-bond forces for HBr. D)larger dipole-dipole forces,larger dispersion forces,and larger hydrogen-bond forces for HBr.

Question

The correct explanation is due to larger dispersion forces for HBr compared to HCl. Dispersion forces increase with the size and mass of the molecules involved. Since bromine (Br) is larger and has a greater mass than chlorine (Cl), HBr will have stronger dispersion forces, leading to a higher boiling point compared to HCl.
