The 68827W student includes several geometries for carbon and nitrogen atoms. From left to right, clockwise, you can see 2 different representations for acetonitrile, acrylonitrile and cyanide. Build these & other nitriles with the Indigo™ Instruments 3D Molecular Model Builder
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for over 30+ years (scroll down to see "Skeletal (Orbit/Minit). These parts are compatible with every molecular model set we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
One way is to show the triple bonding between C and N using the tetrahedral geometries and 3 35mm bonds. The alternative way is to use the 180o linear versions which imply a triple bond. The set comes with enough parts to build all three molecules the standard way but has only 2 each of the linear carbon and nitrogens for building these the alternative way.
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.
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.
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.
