Use cycloalkane molecular models for teaching organic chemistry and biology. Learn about structure, IUPAC naming, conformations, & real-world roles in medicine, biochemistry, & industry

Cycloalkanes are saturated hydrocarbons whose carbon atoms are arranged in a ring, with the general formula CnH2n. Unlike open-chain alkanes, cycloalkanes exhibit unique structural and conformational features such as ring strain that affect their stability and reactivity. In organic chemistry, they provide essential examples for understanding conformational analysis, stereochemistry, and the influence of ring size on chemical properties. In biology, certain cycloalkane derivatives form the structural backbone of steroids, terpenes, and lipid molecules, making them crucial for cell membrane function and hormone activity.

Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for 30+ years. These parts are compatible with every molecular model set we have sold since day 1. This quality may appear expensive but no parts support from other vendors costs even more.

Key Functional Group Cycloalkane Examples for the Classroom

 
Compound Chemistry Focus Biology / Medicine / Nursing Focus
Cyclopropane Extreme ring strain, high reactivity, example of bent bonds. Formerly used as an anesthetic; now mainly of historical interest in pharmacology.
Cyclobutane Ring strain and conformational flexibility; photochemical reactivity. Model for DNA cyclobutane pyrimidine dimers formed by UV damage.
Cyclopentane Low ring strain; envelope and half-chair conformations. Structural component in certain natural products and intermediates in biosynthesis.
Cyclohexane Chair, boat, and twist conformations; axial/equatorial substituent effects. Ring structure found in cholesterol, steroid hormones, and many drugs.
Decalin (Bicyclo[4.4.0]decane) Example of fused cycloalkanes; cis/trans isomerism in fused systems. Framework found in terpenes, steroids, and other bioactive compounds.
 

You can build basic cyclic alkane structures with the basic Orbit Organic Chemistry Set 68845NV. The 4 molecules depicted in the image are from top left going clockwise: cyclohexane, cyclopentane, cyclobutane and cyclopropane.

Bought two of these because I prefer them to the one used at the university. Easy to use and has a good flexibility.

I've had consistently great service from this company. Our students seem to really appreciate the reasonable price. In the years that we've used this product, not one has been returned due to defects.

Considering how many of these we sell to schools every year, that is high praise indeed. Thanks letting us know.
