Start numbering putting the most substituents near the beginning. Also the parent chain is of course one with the most carbons and most substituents. Remember to name substituents in ABC order. Just because there are two methyls which would come out to be dimethyl doesn't mean that you still put...

Many university organic course laboratories use Liebig columns packed with glass beads. This is what I use, but I would like to know if there are better columns that can be used instead of this. I had a problem with this type of apparatuse before. The glass beads shot right through the $30...

I thought you don't need to use filter paper when you already have a fritted disk. Well then again your disk is coarse and the pores are big. You may want to try a finer fritted disk for your filtration. A fritted filter funnel with an outer jacket may help crystallize the product as well.

I'm sure it is through distillation. I believe you could also use anhydrous compounds such as calcium chloride or sodium sulfate to absorb the water from the oil.

Are you using vacuum filtration?

Ok I know that the but-1-ene will form with least abundance, but what about the other two cis and trans isomers? Will they form in equal abundance? That's what I predict, but I just want to make sure. If anyone knows for sure, please reply. Thanks.

When 2-butanol undergoes E1 dehydration, 3 alkenes are obtained. cis-but-2-ene, trans-but-2-ene, and but-1-ene. Which alkene would you predict to be formed in greatest abundance? How do you know?

Four out of eight problems I do not understand. These are the four problems: 1. Given Utility function----Max utility S.T. Budget curve a. How demand changes if p_{1}p_{2}M change whether the good is normal, regular, ordinary b. find demand function x_1x_2 2. Given product...

thanks whozum

This is a basic question. I just want to know what my average is. Homework (6% of total grade): 11 Hmwks each received an avg. of 80 Midterms (60% of total grade): 1) 85 2) 75 3) 75 Final (34%): 51

Find the second-order partial derivatives of the given function. In each case, show that the mixed partial derivatives f_{xy} and f_{yx} are equal. Function: f(x,y)=x^{3}+x^{2}y+x+4 My work (Correct me if I am wrong): \frac{\partial{f}}{\partial{x}}}=3x^{2}+2xy+1...

Thanks guys!

Yes, I forgot to add the constant, but that's what I meant. So I am correct then?

Here's the problem: \int e^{(5x)} This is what I got (Correct me if I am wrong.): \frac{1}{5}e^{(5x)} Or is it just the same: e^{(5x)}
