Several acid halides are shown including phosgene in the middle with a single carbon, propanoyl chloride to the left with 3, butanoyl chloride to the right with 4 and adipoyl dichloride at the top has 6 carbons.
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.
The 68845NV basic set includes 12 carbons and 18 hydrogens and can build any three of the acyl halides shown in the image. These examples can also be built with the 68827W Advanced Chemistry Model Molecular Structures Set .
Every Orbit molecular model set sold by Indigo Instruments is fully compatible with others you might own. You can replenish any set or customize it with Genuine Cochranes of Oxford Orbit Atoms.
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.
