(a) benzene (C6H6) - nonpolar molecules. Only dispersion forces are present.

(b) CH3Cl - Chloroform; polar molecules. Both dispersion and dipole-dipole forces are present.

(c) PF3 - Phosphorus triflouride; has polar bonds but has nonpolar molecule due to its symmetrical structure. Only dispersion forces are present.

(d) NaCl - Sodium chloride; ionic compound. Both ion-ion and dispersion forces are present.

(e) CS2 - Carbon disulfide; nonpolar molecules. Only dispersion forces are present.
