NO MORE

I may sound like combination of troll and Army fanatic, but this is displeasing to me too. The military is important for reasons controversial (lack of reasons being one of them), but I do wish we didn't fund it as much. But I say if there's a system that works for me, then I'll use it. Sorry to make you spend another 250th of a penny on me every year.

I am in organic chem and had my first lab class yesterday, I am doing the assigned questions on our first real lab that must be done in order to actually do it. I have answered most of the questions sufficently, its about TLC plates. I took AP chem in HS but it never prepared me for this, I am totally baffled, dont know how to use any of these machines and really overwhelmed since all of these people aparently did.

But my question is "Arrange the following in order of increasing Rf by TLC: octane, ethanoic acid, dichloromethane, hexanol."

I think its octane, hexanol, and then ethanoic acid. But I dont know where dicholoromethane goes or even why it goes whereever. halp please : (

also I never realized how tough this class would be, I only have it monday nights and then lab wendsdays and we dont even have class next week because my teacher will be in europe or something.
