Build CClFBrH with the Indigo Molecular Symmetry Model Set, 62350, to show the C1 point group, Molymod style.
You can also build the CClFBrH C1 point proup chemical structure with the 62053 university organic stereochemistry molecular model set & the 62009 college molecular model kit for organic chemistry but you will need to use some parts that might not match the same colors or number of holes.
