Alcohol Functional Group Structure Models
SKU: 68827W
Compounds with alcohol functional groups have sp3 hybridized tetrahedral oxygens combined with alkyl groups. Lone pairs are not normally shown, so the 2 prong oxygen atom is used. These form an R-O-H bond angle greater than the 104.5° H-O-H bond angle seen in water. This advanced student set has 24 sp3 carbons so you can build multiple models at once for comparison. You can even make fatty alcohols (long-chain alcohols) which are straight-chain primary alcohols which can have as many as 22 to 26 carbons.
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.
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.
