LOOK BOTH COMPOUNDS HAVE PYRAMIDAL SHAPE WITH LONE PAIR OF ELECTRONS.
ALTHOUGH FLUORINE IS MORE ELECTRONEGATIVE THAN NITROGEN STILL THE DIPOLE MOMENT OF NH3 IS GREATER THAN NF3.
THIS IS BECAUSE THE ORBITAL DIPOLE OF THE LONE PAIR OF ELECTRONS IS IN THE SAME DIRECTION AS THAT OF THE 3N-H BONDS.
WHEREAS IN NF3 THE ORBITAL DIPOLE IS IN THE OPPOSITE DIRECTION AS THAT OF THE RESULTANT DIPOLE OF THE 3N-F BONDS. THE ORBITAL DIPOLE BECAUSE OF LONE PAIR DECREASES THE EFFECT OF THE RESULTANT N-F BOND MOMENTS, WHICH RESULTS IN THE LOWER BOND DIPOLE MOMENT OF NF3.
HOPE THIS HELPS.
PLEASE APPROVE IF I CLARIFIED YOUR DOUBT.
PLEASE COMMENT IF YOU HAVE FURTHER DOUBTS.
THANK YOU.
