Q: How to make 4-cyclohexene-1,2-diol from cyclohexa-1,4-diene?

fmarquez1As the question says, I'm supposed to make 4-cyclohexene-1,2-diol using cyclohexa-1,4-diene: I can use any inorganic reactant, any solvent, and any organic molecule with 3 or less carbons. I am not sure how to go about this question, as I do not know how to use regional-specific reactions. Any h...

Q: What reaction happens between glucose and ammoniom chloride when drying?

WrzlprmftI have the following observations: When I put a solution of glucose (80 g/ℓ) and ammonium chloride (20 g/ℓ) in a drying cabinet at 37°C (maybe a bit warmer) a brown substance forms when all (or most) of the water has evaporated. When I add water to the reaction product, the substance dissolves w...

@Martin-マーチン That's my fault, I think it was me who introduced this Problem—Answer—Question spoil(er)ed scheme. Initially I used it for lengthy implicate posts, and then it slowly became a template for two-sentence HW questions.
Ugly scientific figures: Are scientists lazy, indifferent, or oblivious? And TOC ROFL. And colorfest in scientific publishing. Seriously, if you need more than one accent color for a simple line art drawing, you are doing it wrong.

Q: What is the mechanism for this reaction?

FullBridge The closest reaction I can find is Lossen rearrangement but in that hydroxyamic acid is first converted to its derivative but how will that be possible here? Moreover, even if I make an amine in this step I cannot proceed further, how will the amine and alcohol react in the next step? Any hin...

@andselisk I find this first blog post you have linked rather unhelpful. :(

Q: What is the dissociation percentage of a polybasic organic acid at a certain pH?

EllewelleFor my Master's Thesis I am working with the dicarboxylic acid muconic acid $(\ce{H2MA},$ $\mathrm{p}K_\mathrm{a1} = 2.9,$ $\mathrm{p}K_\mathrm{a2} = 4.0).$ It thus dissociates into $\ce{HMA-}$ and $\ce{MA^2-},$ respectively. I am aware of how to calculate the $\mathrm{pH}$ and the subsequent dis...
