Question

If Hunds rule is applicable, $p^3$ configuration is

$\upharpoonleft$

$\upharpoonleft$

$\upharpoonleft$

because in this arrangement:

• A. electrostatic repulsion is minimum
• B. magnetic attraction with outer magnetic field is maximum
• C. half filled is more stable
• D. all of these

Answer 1

The correct option is D all of these

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.
