Question

I am in chemistry 1, and trying to determine an unknown volatile liquid. I have the boiling point (give or take 3 degrees celsius) which is 85.0 degrees celsius. I also have the molecular weight (give or take 10g/mol) to be 61.05g/mol. Here are pictures of the Infra red spectrophotometry graph which I was told is basically the finger print of a substance. Do you know what substance this volatile liquid is?
