Lecture 1: Introduction to Molecular Orbitals
Objectives and Skills
KEY INFORMATION SUMMARY
PROBLEMS
Problem 1.1: Atomic Orbitals
- Sketch and label the three 2p atomic orbitals of nitrogen. SOLUTION
- How many electrons would be filled in each 2p orbital? SOLUTION
- Determine the complete electron configuration of nitrogen. SOLUTION
Problem 1.2: Valence Bond (VB) Theory
- Draw the VB theory orbital overlap for HCl. SOLUTION
- Explain why a resulting bonding orbital is lower energy than an initial atomic orbital. SOLUTION
Problem 1.3: Molecular Orbital (MO) Theory
- Draw the MOs that result from the combination of a hydrogen atom and a helium atom. SOLUTION
- Draw the MO diagram for H-He. Fill in the electrons, determine bond order, and whether or not this would be a stable molecule. SOLUTION
