Lewis Structure & Atom Charge – Organic Chemistry Quiz
Check the box next to each molecule on the right that has the shape of the model molecule on the left:
Answer
You can drag the slider to rotate the model molecule.
Note for advanced students: the length of bonds and size of atoms in the model is not necessarily realistic. The model is only meant to show you the general geometry and 3D shape of the molecule.
