Question

On the basis of molecular orbital (MO) theory explain the following:
(a) Stability of molecules
(b) Magnetic nature of molecules​

Answer 1

$\huge\underline\frak{\fbox{AnSwEr :-}}$

(a) Stability of molecules : If in a molecule the number of electrons in bonding MOs is greater than the number of electrons in antibonding MOs, then the molecule is stable.

(b) Magnetic nature of molecules : If all MOs in a molecule are completely filled with two electrons each with opposite spins, then their spin moments are cancelled and the molecule is diamagnetic and repelled by magnetic field. However if one or more MOs are half filled with one electron, then the molecule is paramagnetic and attracted by magnetic field.

Answer 2

Explanation:

your answer is here

ANSWER

Molecular orbital structure of H 2is.

Bond order = 2

Bonding electrons−(non−bonding electrons)

= 22−0=1⇒ Bond order.

There is no unpaired electrons in H 2

. So, the H 2

molecule is stable and Diamagnetic.
