Worksheet: Molecular Orbital Coefficients in Hückel Theory

In this worksheet, we will practice using the secular equations in Hückel theory to estimate the energy level diagrams of conjugated molecules.

Q1:

Fill in the blank: Based on the Hückel molecular orbital theory, the LUMO of conjugated cyclobutadiene (CH)44 has the energy of .

  • A𝛼+2𝛽
  • B𝛼+𝛽
  • C𝛼−𝛽
  • D𝛼−2𝛽

Q2:

Fill in the blank: Based on the Hückel molecular orbital theory, the highest occupied molecular orbital (HOMO) for the benzene molecule has an energy of .

  • A𝛼−2𝛽
  • B𝛼−𝛽
  • C𝛼+𝛽
  • D𝛼+2𝛽
