# How many isomers can a formula of C_3H_5Cl_3 generate?

#### Explanation:

these are the possible structures

I think I can count 5 structural isomers.

#### Explanation:

$\text{1,1,1-trichloropropane}$;

$\text{1,2,3-trichloropropane}$;

$\text{1,2,2-trichloropropane}$;

$\text{1,1,2-trichloropropane}$; this has 2 stereoisomers, with the chiral centre at ${C}_{2}$;

$\text{1,1,3-trichloropropane}$;

All these names (I think) are unique, which is a good indication that they are distinct compounds. Again, this is a good demonstration of the richness of carbon chemistry: a saturated carbon chain with 3 carbon atoms, with only 3 of the same heteroatoms, and yet (at least!) 5 structural isomers. How can organic chemists make anything unique?
