Lesson Worksheet: Hybridization of Main-Group Elements Chemistry • 10th Grade

In this worksheet, we will practice defining hybrid orbitals and assigning the hybridization of main-group atoms based on their electron pair geometries.

Q1:

The hybridization of the nonhydrogen atom is the same in all but one of the following molecules. In which molecule is the hybridization different?

  • ANH3
  • BAlH3
  • CHO2
  • DPH3
  • EBH26

Q2:

The hybridization of the central atom is the same in all but one of the following molecules and ions. In which species is the hybridization different?

  • AAluminum trichloride
  • BSulfur trioxide
  • CSulfite
  • DNitrate
  • ECarbonate

Q3:

The tetrathionate anion contains two types of S atoms:

OSSOOSS2OOO

What is the hybridization of the S atoms in the SO bonds?

  • Asp2
  • Bsp3d2
  • Csp
