Hexachloropropane

Hexachloropropane is a chemical made from propane where six hydrogen atoms are replaced by chlorine atoms. Its formula is C3H2Cl6. Because the chlorine atoms can attach to different carbon atoms on the three-carbon chain, hexachloropropane has several isomers, or different structures of the same molecule.

The three common types of isomers are:

- End-dominant: three chlorines on each end carbon, none on the middle carbon.
- Even: two chlorines on every carbon.
- Mixed: three chlorines on one end, two on the middle carbon, and one on the other end.

All these isomers share the same formula but have different arrangements of chlorine atoms.
