I came up with 3-propylpentane, would that be correct?

Find the longest carbon chain.

Sorry about that was suppose to have been 5 in the longest chain.

OK 5 carbon chain. What about the substituents?

I came up with 2 propyl 2-butyl 4-ethylhexane, but am unsure if this is correct?

It's on the third carbon (so 3-) and there are 3 substituents (so Prop)...

3-prop

No, there are two substituents on that carbon.

No, where do you get ethyl from, there are only two 1 carbon substituents on that middle carbon. If that makes sense.

kind of so what your saying is I count the one to the left and the one to the right but not the carbon that is in the longest chain. So essentially it would be 2-methyl 2-methyl...

joshphillips1977:  I hope you don't mind me merging your two threads on nomenclature.  Once you figure out one, you may have what you need to solve the other.  Sorry if the order is a little screwy for you and everyone else though.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
