The five sp3 d hybrid orbitals are directed in direction of the five comers in the trigonal bipyramidal. Hence, the geometry of PCl5 is usually represented as:
In NH3, the dipole moments of the three N—H bonds are in precisely the same path given that the lone pair of electron. But in NF3, the dipole moments in the 3 N—File bonds are within the way opposite to that of your lone pair. Therefore, the resultant dipole instant in NH3 is more than in NF3.
