Lesson Worksheet: Conjugated Systems in Molecular Orbital Theory Chemistry
In this worksheet, we will practice using particle-in-a-box and node-counting arguments to predict molecular orbital diagrams for conjugated molecules.
Q1:
Butadiene contains two occupied bonding orbitals and two unoccupied antibonding orbitals. The electrons are delocalized between the four atoms.
Which of the following diagrams illustrates the bonding orbital with the highest energy?
- A
- B
- C
- D
- E
An electron is added to a butadiene molecule. Which of the following diagrams illustrates the antibonding orbital occupied by the additional electron?
- A
- B
- C
- D
- E
