Re: How to draw curved arrows?

The arrow is going from one bond to another bond because that bond is breaking, and those electrons are being used to form a double bond between oxygen and carbon. You can figure this out by looking at the product of step 3: the R and NH3 do not change during step 3, but the two C-OH bonds change. W...

Re: Final 2013 6a Numbering a hexene

Just a note: I find it helpful to think about it in terms of money: for example, $1.99 is less than $2.11, so you would go with 1,9,9, regardless of the fact that the numbers that follow the 1 are higher than the numbers that follow the 2

Re: Naming an Organic Molecule with Multiple Functional Grou

I don't think we need to know how to name a compound with multiple functional groups. We didn't go over anything like that in class. I think at most we need to be able to identify the different types of functional groups that are present within a single compound (given a line structure).

Deriving half life (2011 Final, Q4e)

Can someone explain how question 4 part e was solved? Where does the 2^(n-1) come from??

Numbering In cycohexane (2013 final, Q6A)

Hello. I am confused on how the substituents were numbered in this problem. I got 2,3,4,4-tetramethylcyclohexene as the name, but the solution has 1,5,5,6-tetramethylcyclohexene as the answer. Why is it numbered this way? I thought you want to minimize the numbering (lowest to the double bond), so t...

Re: Torsional and steric strain #3.9

How do you know that the substituent groups are both on the top of the carbons, rather than opposite of each other (one on the top of a carbon, the other on the bottom)?

Alcohol Classifications

Hello! Some chapter 2 homework problems asked us to give the alcohol "classification"- do we need to be able to do this? If so, how are they classified?

OChem Worksheet (Confusion on wording)

Hi. I'm a little confused about question 12. Should the final molecule that you are naming have 3 methyl and 1 ethyl group, or should it have just one methyl and one ethyl group (because in part 4 we already replaces two axial hydrogens with CH3)?

Thank you for any clarification!

Distinguishing Reactions (14.89)

In the solutions guide, it says that "in a highly concentrated solution of sucrose, the concentration of of water will change during the course of the reaction" - can someone explain why this is true (water is contained in the rate law for this elementary step)?

Arrhenius Equation for two temperatures (14.59)

Hi. Could someone explain how we got the equation ln(k'/k)=(Ea/R)((1/T)-(1/T')) that is given in the solutions manual?

Re: Why is Ka the square root of K

Further, you cannot simply divide the reaction by two (to get a coefficient of 1 for everything), since the cell potential (E) would then be for a different equation (and you cannot simply divide the cell potential by two).

Cell Diagrams- inert metal and order

When do we need to put an inert metal in the cell diagram (such as Pt(s))? Also, does the order of the substances within the cell diagram (separated into anode and cathode) matter? Should the elements go in the order of the reaction (from reactants to products) or is it irrelevant?
