Question

What is the propane gas chemical formula?

Answer 1

`"Propane is"` `C_3H_8`.

Explanation:

OR, if we draw out the hydrocarbyl chain, we get `H_3C-CH_2-CH_3`.

And of course propane is an alkane, i.e. `C_nH_(2n+2)`. Would you expect propane to be more volatile than methane, `CH_4`; what about butane, `C_4H_10` Why or why not?
