Optional Style for Double & Triple Bonds
SKU: 68845NV
Optional "x-pegs" fit holes in trigonal and linear carbon atoms to depict double & triple bonds differently from the standard parts included in this set. This style produces flattened structures such as the purine & pyrimidine nucleotides in our 12 base pair DNA model.
The model on the left is benzene which requires 5 extra sp2 trigonal carbons (1 comes with the set) & 6 optional x-pegs. The double bonds are 20mm long while the single bonds are 30mm. Immediately to the right is ethene which uses 2 sp2 carbons, 4 x-pegs & 2 20mm bonds.
The upper right model is ethyne which requires an additional 180o linear carbon (1 comes with the set), 4 x-pegs & 3 20mm bonds.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for over 30 years. These parts are compatible with every student & teacher 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.
