If Hunds rule is applicable, $$p^3$$ configuration is $$\upharpoonleft$$ $$\upharpoonleft$$ $$\upharpoonleft$$ because in this arrangement:

Aelectrostatic repulsion is minimum
Bmagnetic attraction with outer magnetic field is maximum
Chalf filled is more stable
Dall of these
Correct Answer

Solution

In the case of:


$$\upharpoonleft$$
$$\upharpoonleft$$
$$\upharpoonleft$$
the arrangement of all electrons is in a different orbital that results in a minimum force of repulsion. As all are in the same spin, therefore magnetic attraction due to external field is maximum. Half filled orbitals are more stable because of high exchange energy.
