Hello, I've been asked to find the percent composition of 4 compounds (1 and 2 butanol, 1 and 2 bromobutane. The one I've provided is the GC of 2-butanol. How do I find percent composition of this compound?
Also, explain why the 4 reactions give you different product compositions by analyzing each of the reactions: what set of reaction conditions relate to what kind of product distribution and what does that tell you about the operating mechanism and the factors that affect product distribution?
