Determine the enthalpy of reaction for the conversion of butane, C4H10, to butanol, C4H9OH.
the graphs arent showing up on here but the numbers are H=-2881.9 and H=-2712.9
the answers I could get are
a. 169 kJ/mol
b. –169 kJ/mol
c. 5594.8 kJ/mol
d. –5594.8 kJ/mol
and I am not sure which one because I am doing a course online and It's hard trying to teach yourself.

To go from butane to butanole, what kind of process is it? What enthalpy these processes obtain?

They won't till you attach them them to your post as a picture.
but the numbers are H=-2881.9 and H=-2712.9
Sorry, no way we can be sure what you mean. We can do some wild guessing at best.

You can append pictures to your messages by "additional options" > Attach. That would help. I don't see what your H numbers are, clearly not the enthalpies of formation. Bond energies maybe? In any case, don't forget the units: they are not only a part of a physical value, they also help you check if your computations make sense.
I dislike something in your question. "Butane to butanol" is not a reaction. The oxygen atom comes from somewhere: from a molecule that has been broken. This used or released enthalpy too. You have to know what the complete reaction is to determine an enthalpy of reaction.
