Guess the Mechanism help (Organic Chemistry)

AI Thread Summary
The discussion centers on determining the mechanism for converting a diol into a ketone through spectral analysis. The initial hypothesis involved tautomerization, where oxygen atoms donate electrons to form a double bond, but this approach was unsuccessful. Ultimately, the solution identified is the pinacol rearrangement, which was not covered in lectures. This realization highlights the challenge of applying theoretical knowledge to practical problems in organic chemistry. Understanding the pinacol rearrangement is crucial for grasping the conversion process in this context.

"Guess the Mechanism" help! (Organic Chemistry)

Homework Statement


After identifying my reactants and products via spectral analysis, I am now tasked with figuring out the mechanism behind converting a diol into a ketone.

The Attempt at a Solution


The key to this appears to be tautomerization somewhere in the reactant (whereby the oxygen atoms donate electrons in order to create a double bond), but everything I've tried with that has failed so far. I'm really stuck.

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...
