Any suggestions for the stereochemistry of this reaction?

Homework Statement I was given the reaction in the attachment, and asked to find the product. 2. The attempt at a solution My understanding is that water can open epoxide rings, in an acidic environment. And so, I would figure that the product is 1-methyl-1,2-cyclohexanediol. I don't know...

Thanks Borek. I didn't see that one.

Homework Statement I am given the structures for 2-nitrophenol and 3-nitrophenol, and asked which one has the higher pKa and why. Homework Equations pKa=-log(Ka) The Attempt at a Solution I looked up the pKas in a reference and found the pKa of 2-nitrophenol to be 7.17 while the pKa of...

So, would you, the wise ones who have gone through the applications before, say that if I apply to about 10 programs, I would have a good chance of getting into at least one? I will also be applying for some on-campus research and some non-REU sites. I really, really do not want to end up doing...

My lab instructors are professors, so I might be able to use them as recs. I guess I'll just talk with them one-on-one to determine whether they think they can write a good letter. I did my research at a different college during high school. I guess I could go for a rec from him, as the...

At my school, we have different profs for class and lab. Which do you think it would be better to get recs from? I'm a little concerned that my professors don't know me well enough to write good recs because I did research with them. Is that a problem, do you think? Peter

Hi everyone, This summer I spent a lot of time looking at possible research sites for next summer. I was wondering if anyone out there could gauge the odds of me landing a research project. I am entering the sophomore year at St. Olaf College (a small Liberal Arts school in Southern...

I got it. Every time the reactant is changed into product, the pressure is one half for that molecule. So I found the values of the reactants and the products, and found the order is 1. Thanks for the help, Peter

Yes, I know how to diagonalize the matrices.

Any help?

Homework Statement A = {{2,1,0}{0,-2,1}{0,0,1}} and B = {{3,2,-5}{1,2,-1}{2,2,-4}} Show that A and B are similar by showing that they are similar to the same diagonal matrix. Then find an invertible matrix P such that P-1AP=B Homework Equations P-1AP=B, or AP=PB The Attempt at a...

Homework Statement I am considering the reaction 2C4H6 --> C8H12 at 320 degrees C. Both the product and the reactant are gases. I have the data: Time (minutes): 0.00 3.25 12.18 24.55 42.50 68.05 Total P (torr): 632.0 618.5 584.2 546.8 509.3 474.6...

I am looking at this equilibrium: H2O + D2O <-> 2DHO (D = Deuterium) I have 2.0 mol of H2O, 1.0 mol of D2O and 2.0 mol of DHO. What are the equilibrium amounts of each of the molecules? What I tried: 6 mol of H, 4 mol of D H2O: P(X=H) & P(Y=H) = 9/25 D2O: P(X=D) & P(Y=D) = 4/25 HDO...
