Question

I have to answer the following questions about C3H7Cl:

Are there different constitutional isomers for this formula, are there different cis/trans isomer, and are there different conformers?

I know that C3H7Cl can be drawn two ways:

H-C-C-C-Cl With H's above and below the 3 carbons

H-C-C-C-H with H's above and below the carbons and a Cl on one of the carbons.

I am not sure if these two ways would be considered conformers or constitutional isomers?
