The dipoles moment of `NF_(3)` is less than `NH_(3)` because

Dipole moment of NF_(3) is smaller than :

Dipole moment of NF_(3) is smaller than :

Statement-1 : Dipole moment of NF_(3) is less than that of NH_(3) . Statement-2 : Polarity of N-F bond is less than that of N-H bond.

Statement-1 : Dipole moment of NF_(3) is less than that of NH_(3) . Statement-2 : Polarity of N-F bond is less than that of N-H bond.

NF_3 and NH_3 show dipole moment.But the dipole moment of NF_3 is less than that of NH_3 .Why?
