The 68827W student set includes 30 carbons, 50 hydrogens and enough oxygens to build all 4 of the ether molecules shown in the image: di-tert butyl ether upper left; di-isopropyl ether to the right; dimethyl ether lower right; and methyl ethyl ether to the lower left. Build these & other ethers with the Indigo™ Instruments 3D Molecular Model Builder
The models are shown using 20mm bonds for C-H and 30mm bonds for C-C.

Every Orbit molecular model set sold by Indigo Instruments is fully compatible with others you might own. You can replenish any set or customize it with Genuine Cochranes of Oxford Orbit Atoms.
Good kit. Fast delivery. It made visualizing chair/boat conformations easier, helped figuring out chirality and stereochem as well. The clear bonds however were sometimes hard to work with as you really need to shove the parts into them, and can slow you down if you're able to use a model kit in exams. As a result, I like using the more rigid grey bonds for most of my builds. The bendable bonds are good if you need to visualize your alkenes and alkynes.
Thanks for the feedback. The rigid bonds are great for chair boat flips but eventually wear out with repeated use. The clear bonds are tougher to work with at first but eventually loosen up enough to make them easier to use. They will last over many more uses which is good if you are taking chemistry as a degree.
Good quality and assortment!
These are great kits for a great price. Very useful, and easy to buy extra parts if you want.
Glad to hear it. This model set is supported by our 3D Molecular Model builder so any time you want to augment it, the tool will tell you what you need.
