Answer:
[tex]C_3H_7Cl[/tex] = Two structures
[tex]C_3H_6Cl_2[/tex] = Four structures
Explanation:
We must remember that in an isomer we have the same molecular formula but different structures. Thus, for the molecule [tex]C_3H_7Cl[/tex] we can draw a linear structure of 3 carbons and change the position of the chlorine atom, obtaining two different structures.
For the molecule [tex]C_3H_6Cl_2[/tex], we can use similar logic. Place a chain of 3 carbons and change the position of the chlorine atoms in such a way that for this formula we will have 4 different structures.
See figures 1 and 2 for further explanations.
