Understanding the Arrow Notation in Organic Chemistry Elimination

AI Thread Summary
The discussion revolves around the interpretation of arrow notation in organic chemistry, specifically in the context of E2 elimination reactions. Participants seek clarification on whether the arrow indicates cis or trans orientation and how it relates to the abstraction of a beta hydrogen by a small base like ethoxide. The conversation highlights the importance of considering the resultant species after proton abstraction and its stability compared to isomers. Understanding these factors is crucial for predicting the major product, which is likely to be the Zaitsev product in this scenario. The discussion emphasizes the need for clarity in interpreting arrow notation for accurate chemical analysis.

Can anyone help me with this ?
What does the arrow mean ? Is it cis or trans,the base is small so it should be an E2 elimination with zaitsev product.Though I think it may be due to the beta hydrogen being unavailable,but I do not know whether the arrow means from the upper or lower /cis trans side ?

I’m assuming the arrow means that this proton is abstracted with the ethoxide base. For the product, consider two things: 1) what is the resultant species from abstracting that proton, and 2) what is its stability relative to its isomers.

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...
