This student molecular model set is unique in having trigonal bipyramidal carbon atoms. They can show SN2 reaction mechanisms where one bond is broken and another is formed in synchrony.

Details

In our video we show the conversion of a secondary alkyl halide to a nitrile. An SN2 reaction leads to an inversion of the chiral center of the substrate molecule. SN2 reactions are one of the most important in Organic Chemistry, demonstrating a concerted backside attack and the importance of steric hindrance.

Exactly what I was expecting. I appreciate that it also comes with a piece that helps you remove the connector pieces so it is easy to use. They kept me informed without sending too many emails. Shipping was faster than expected too.

It was good for the first 3 chapters of orgo. I made functional groups and was able to visualize them better thanks to this kit. However once you get into chair and boat conformations, they were much too jangly and plyable to be practical. None of the bonds provided are stiff enough to help with stereochemistry. They are well made as they are. I just did not find them useful for stereochemistry. I'll probably keep them in functional groups for recognition and testing.

Thanks for the feedback. Chair boat can be tricky. If you position your fingers the same way we show with the magnetic version, it will work better. See the video for "cyclohexane". You can actually feel the difference between the chair (resistant) & boat (low resistance).

Very easy to use and plenty of pieces, so you don't fall short when building compounds. It helps when visualizing the structure of elements and especially when producing constitutional isomers of compounds.

It you ever need to augment this set, we carry a complete line of atoms and bonds & you can use our 3D Molecular Model Builder to determine what you need.

Just as described. Super fast shipping!!!

It is a solid product that is easy to work with. The pieces do not get too stuck together nor do they fall apart from each other. It is helpful to have in lecture, and I'd buy more from them if I needed to.

We ordered ten new sets and a bunch of spare bonds. Came very quickly (like next day!) Staff were super helpful when I called to order.

Model kit came exactly as expected, and it came fairly quickly. Would recomend for organic chemistry students.

Really helpful for organic chemistry courses. A little bit hard at first and had some edges that I had to file.

— Indigo: The bonds are a tight fit initially but this ensures that the models still hold together well in 4 years! A little bit of dish soap is the simple fix.

Our school purchased a couple of class sets from Indigo. They were nice enough to look at our original order, and offer an alternative that gave us the same number of pieces but at a reduced cost. They also worked with us to modify the contents so that we could get more of a certain type of atom than was originally listed. Overall, a great experience.
