Textbook Problem

Among the following, which has the shortest bond and which has the longest: Li2, B2, C2, N2, O2?

Interpretation Introduction

Interpretation:

Molecules with longest and shortest bond length have to be determined from the given molecules.

Concept Introduction:

Bond order: The bond order has defined as the net number of bonding electrons pairs linking a pair of atoms. This same concept can be applied directly to molecular orbital theory, but not bond order is defined as.

Bondorder=12(NumberofelectronsinbondoingMOs-NumberofelectronsinantibondingMOs)

Bond length of a molecule decreases with increase in bond order.

Explanation

Bond order of all the given molecule can be determined as follows,
