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...

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

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).

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

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...

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)?

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?

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!

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)?

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?

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).

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?
