I did, but combined with the lecture, I got really confused and the prof. is not helpful at all.
Here's a pattern I derived from all the related notes/websites/exams I read:
In an electrocyclic addition:
Even double bonds with trans product = thermal + conrotatory...
I understand now, I was thinking of sigmatropic rearrangements. It is like a Diels-Alder reaction then?
Suprafacial is when we have bonding of lobes of the same sign, while antarafacial has bonding of lobes of the same side as well as bonding of lobes of opposite signs.
Do we have to draw the...
Yes, the way I do it (correct me if I am wrong) is to count around the new sigma bond. The "1" would be the carbon attached to CO2Et, and "2" the other side of the double bond where the new sigma bond will be (hence the "2"), while the "4" comes from counting from the other side ("1" being the...
I am sorry, I still don't have a clear understanding of what I should do. Could you please tell me how you would reason for just the 1st problem? Thank you!

Hi!
The teacher told us today about a formula. In order to find the number of genes, you need to see how many offsprings we got: here it would be 64 (By total # I mean as low as we can go and still keep a category. Here 1/64 is the minimum).
1/(4^n)=64
n= number of genes and so in this case...
Thank you so much!
I have another question regarding the codominant alleles:
If we cross a white plant with a red plant, and they have codominant alleles, we will get all pink plants in F1, and then a range of colors from white to pink to red in the F2.
Now, let's assume we go several color...

Hello,
I thought I understood how to answer the questions (posted below, please follow the links) but apparently my reasoning is flawed.
Any help is appreciated!

Thank you so much, you're so helpful!
We rarely get the mechanisms in class, as we are told we have to do a lot of memorization. But I found that understanding the mechanism allows me to remember the reactions for the rest of the semester, instead of relying on memorization.
Hello,
I need to make sure I understand some of the reactions correctly... For example:
CH2OHCH3 in H+ will give us CH2=CH2. I would think that here the H+ bonded with the OH resulting in H2O (a leaving group), but I am not sure what happens to the other leaving H.
In RC≡CR' in Na/NH3...
