Carboxylic acids are organic acids characterized by a carboxyl group (-C(=O)OH) as seen in the familiar acetic acid (vinegar), shown at left in the image.

Carboxylic acid formulas are designated as R−COOH or R−CO2H, where R refers to an alkyl, alkenyl, aryl, or other group. Carboxylic acids are very important biologically & include amino acids and fatty acids.

Use in conjunction with our 3D Molecular Model Builder (pick Orbit flexible style) to learn/confirm carboxylic acid nomenclature. It recognizes common names such as butyric acid & its IUPAC equivalent, butanoic acid; formic acid/methanoic acid. This set's 24 sp3 carbons can even build large carboxylic acid structures such as the fatty acids palmitic acid (hexadecanoic acid-palm oil), stearic acid (octadecanoic acid-soaps), & arachidic acid (icosanoic acid-peanut oil; choose the NCI database for the latter).

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.
