Old NobbyOrganic Chemistry 239 Piece Model Kit - Molecular Model Kit with Atoms, Bonds, Instructional Guide, Bond Removal Tool, and Bonus Molecular Stencil

I am taking Orgo 1 now and this kit is perfect. My professor has us use it to model structures in class and even on exams. My friends with slightly cheaper kits have had some trouble, but this is kind of the right balance between sturdy and not-too-expensive. Highly recommend. It also comes with a stencil for organic chemistry shapes which I didn't realize and is really nice. All of the bits also have resealable plastic bags which is helping me keep it organized. The lid of the box doesn't stay on without rubber bands though which makes it a bit of a hassle to carry around.

The molecular sets we had were difficult to assemble, so we looked for sets that had pieces that didn't take much effort to put together. The pieces in the models do not fall apart after the models are assembled as well. There are plenty of pieces in the kit for our students to assemble all the required models for this class.

Perfect for my daughter's Chem II class.

This set works great when you are in class and need to visualize molecules. The colors are very diverse and the pieces are durable and stick well together. The one drawback is that after opening the packages, the pieces (no matter what) will get very jumbled and disorganized. Hard to find the pieces you are looking for and easy to spill out of container. Would be better if there were individual lids to each atom color and bond.

The included stencil is a really nice bonus.

It was incredibly helpful to be able to visualize the molecules in 3 diimensions. The pieces fit snuggly and are relatively easy to assemble. I was so impressed, I immediately ordered the Supplementary Kit. Great product.

I just received the kit in the mail this evening and my only regret is that I wish I would have purchased this sooner. I was able to get through a full year of General Chemistry without using any models but I got to a breaking point with Organic Chemistry. This would have been so helpful when I was learning how to conceptualize Newman Projections, but I was able to work really hard and mostly get by. Chirality and assigning absolute configurations feels basically impossible without the model kit.If you’re taking O. Chem, do yourself a favor and buy the kit as early into the term as possible. Skip a few meals. Mow your neighbor’s yard. Sell something on eBay. Do what you need to do to get this kit.The molecules are really easy to build and pretty sturdy (especially if you’re mostly building chains with some methyls throughout the carbon chain and some functional groups here and there). However, if you build a ring structure like a hexene with some significant groups, the weight of it will pull on some parts of the structure a little. As long as you’re using both hands, this isn’t problematic, and really, we want the pieces to be flexible. I found the weight to be a little cumbersome when I built t-butyl-3-fluorine-3-methylcyclohexane, despite using two hands. But really, it was just the t-butyl group that was the thorn in my side.All in all, I’m really pleased with this purchase. There’s tons of pieces and I like that the box it comes in is partitioned off into 4 sections so you don’t have to keep the atoms and bonds in the baggies in order to keep them organized.

I bought two sets for my HS chem class and they work fine to illustrate simple chemical structures. The longer bonds used to create double bonds are a little tough to connect initially but overall not bad. The price is very good for all you get although it’s hard to get everything back on the box!
