AI Thread Summary
Detecting enantiomeric excess using 1H NMR on a 400 MHz instrument without chiral agents is not feasible, as enantiomers exhibit identical NMR spectra in achiral environments. This means that without the introduction of a chiral agent, it is impossible to differentiate between the two enantiomers based solely on their NMR signals.

is it possible to detect the presence of enantiomeric exess of one enantiomer over the other using 1H nmr in a 400 mhz instrument without the use of any chiral agent?

No, enantiomers should have identical NMR spectra in an achiral environment.
 

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
