About This Product
This orbital model set is used to demonstrate sigma-bonding and pi-bonding in four hydrocarbons, and through them the concepts of electron delocalisation and orbital hybridisation. The carbon spheres come with different numbers of holes for the different bonding arrangements, and separate pieces represent the pi-bonds.
Frequently Asked Questions
Which molecules can be built with this set?
The set has sufficient parts to make models of benzene, ethane, ethene and ethyne.
What concepts do the models demonstrate?
They demonstrate sigma-bonding and pi-bonding, and therefore electron delocalisation and orbital hybridisation.
