Co2 and cH4 have zero dipole moment as these are symmetrical in nature. Between NH3 and Nf3, NF3 has greater dipole moment though in NH3 and NF3 both N possesses one lone pair of electrons.
This is because, in the case of NH3, the net N_H bond dipole is in the same direction as the direction of the dipole of the lone pair but in the case of NF3, the direction of the net bond dipole of three N_F bonds is opposite that of the dipole of the lone pair.
NH3 has the maximum dipole moment.
