Chapter 5, Problem 5.56SP

(a)

Interpretation Introduction

Interpretation:

The bond order of ${\text{C}}_{\text{2}}$ has to be determined.

Concept introduction:

Bond order:

• Bond order is nothing but the number of chemical bonds that involved in between a pair of atoms.
• Bond order indicates the stability of a bond and it reflects the stability of the molecule.
• An element having bond order zero value is not exit in the universe, but compounds may have a bond order of zero.
• According to molecular orbital theory bond order can be calculated by using the following formula.

$\text{B}\text{.O =}\frac{\text{number of bonding electrons - number of antibonding electrons}}{\text{2}}$

(b)

Interpretation Introduction

Interpretation:

The requirement of electrons to increase the bond order of ${\text{C}}_{\text{2}}$ molecule has to be given.
