The molecular orbitals for linear and cyclic H 3 + should be calculated and displayed. Concept introduction: The formation of molecular orbital takes place by mathematical combination of wave functions of atomic orbitals possessing nearly same energies of the atoms involved in bond formation. The number of molecular orbitals formed are always equal to the number of atomic orbitals involved. Thus, the orbitals which have lower energies compared to atomic orbitals are bonding orbital and those which have higher energies compared to atomic orbitals are antibonding orbitals.

Chapter 5, Problem 5.43P

a.

Interpretation Introduction

Interpretation: The molecular orbitals for linear and cyclic H3+ should be calculated and displayed.

Concept introduction: The formation of molecular orbital takes place by mathematical combination of wave functions of atomic orbitals possessing nearly same energies of the atoms involved in bond formation. The number of molecular orbitals formed are always equal to the number of atomic orbitals involved. Thus, the orbitals which have lower energies compared to atomic orbitals are bonding orbital and those which have higher energies compared to atomic orbitals are antibonding orbitals.

b.

Interpretation Introduction

Interpretation: The species that is more likely to exist should be determined.
