- Using VSEPR theory, count the number of bonds (b) and lone pairs (lp) in a molecule or ion central atom.
- Be sure to count once multiple bonds; i.e., for the purpose at hand, a triple or double bond is counted once. So for the central atom in
- HCN, b = 2 and lp = 0.
- CO2, b = 2 and lp = 0.
- SO2, b = 2 and lp = 1.
- Submit b and lp through our form.
What is/is not reported?
The tool reports for the central atom its
- electron arrangement.
- molecular geometry.
Who can use this tool?
- Data miners, computational chemists, chemical engineers, chemists, and chemistry teachers and their students.
- Try the following cases:
- Nitrosyl Bromide
- Hydrogen Selenide
- Nitryl Fluoride
- What would be the electron arrangement and molecular geometry associated to a central atom that
- has 5 bonds and 2 lone pairs? Why?
- has 4 single bonds? Why?
