Chemistry Are there alternative hydrogen abstraction pathways in E2 elimination reactions?

AI Thread Summary
The discussion focuses on determining the reaction mechanism for an E2 elimination reaction involving hydrogen abstraction pathways. The user has successfully identified the formation of one alkene but is seeking clarification on how to obtain a second alkene. There is a specific inquiry about whether other hydrogen atoms can be abstracted by the hydroxide ion (OH-). The conversation emphasizes understanding the mechanisms of E2 reactions and the role of hydroxide in hydrogen abstraction. Overall, the thread seeks to clarify complex reaction pathways in organic chemistry.

Hey,
I have this equation in which I have to determine its reaction mechanism.

I managed to determine how we managed to obtain this the molecule in the picture above, but I don't understand the mechanism behind obtaining the second alkene. Thank you so much for your help, and sorry if the vocabulary is incorrect since I translated this from french.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
