Instructions This worksheet will help you practice, build, and draw 3D structures on paper (sawhorse and Newman projections). You will use the understanding of the 3D shapes of molecules to start identifying types of strain, and assessing the energy of stability of different conformational isomers.
Organic molecules are three-dimensional structures. It can be difficult to work with the 2D representations between these structures if you can't visualize them. Actively engaging with virtual models or handheld models, can increase your understanding.
Possible methods for visualizing these molecules:
Use https://molview.org/ to build structures that you can rotate and zoom in a video tutorial for using MolView [Transcript] Buy a hand held model kit: one suggested kit on Amazon Build models with marshmallows and pretzels ChemTube provides a 3D projection: Conformations of ethane – Newman projection Remember, you can work through the worksheet while watching the videos and using the readings for reference.
