Chapter 21, Problem 21.15P

(a)

Interpretation Introduction

Interpretation:

The number of 2p orbital electrons in each molecule or ion has to be stated.

Concept Introduction:

2p orbitals and their electrons:

There are three types of 2p orbitals such as 2px,2py and 2pz orbitals. The bonding between two 2px orbitals will be π-bonding which result in the formation of double bond. Similarly, the bonding between two 2py  orbitals will also be π-bonding which also result in the formation of double bond whereas the bonding between two 2pz will be σ -bonding which result in the formation of single bond. Generally, a chemical bond is formed by the interaction of two electrons. So, a double bond formed by 2p orbitals will obviously hold two electrons.
