Chapter 14, Problem 3DQ

Interpretation Introduction

Interpretation:

The difference in give figures needs to be identified. As B₂ is known to be paramagnetic, the ${\text{π}}_{\text{2p}}\text{, and }{\sigma }_{2p}$ MOs must be switched from our first prediction, this need to be rationalized. Also, ${\sigma }_{2p}$ contains lower energy than ${\text{π}}_{\text{2p}}$ , reason for this needs to be explained.

Concept Introduction :

The wave nature of electrons is assumed by molecular orbital theory, so through the overlapping the wave functions of dissimilar atoms interact in two ways- Constructive interreference and Destructive interference. The molecules possessing higher number of bonding electrons are more stable.
