Question

Dipole vectors in nh3

Answer 1

Answer:

In,NH3 the nitrogen being more electronegative and so the N-H bond is pointing towards N. ... In NH3, the (3) H-N and (1 ) N-lone pair dipoles are in the same direction. That is, the H-N dipoles strengthen and reinforce the lone pair dipole. Therefore the vector sum of the four dipole moments is high (1.46D).

Answer 2

Answer:

This is because NH3 has a three-fold rotational axis. As a result, we can say that the dipole moment along each N−H bond is identical.
