Hi everyone.
I have recently made an unknown sample that I isolated and purified. I am working on the structural elucidation, but something peculiar happens when I add solvent to the unknown.
The crystals are normally yellow (and an acetone solution is...

For fun examples see Nile Blue or Nile Red!), maybe you could try different solvents as well and see if there is a correlation between the solvent.
From green to colorless to yellow depending on the solvent.

Hi,
I've been doing an HPLC experiment on cinchona alkaloids and I want to explain why Quinidine eluted from the column before Quinine, in terms of its polarity.
I was just wondering if any of you know any know of any good sites or could help me? I know...

Arkcon,
Those two compounds are optical isomers column has no chirality, and there was no mention of a chiral auxiliary in the solvent system.
Has more carbons per polar functional groups.

URGENTE:perche nell'estrazione con solvente nell'acqua si scioglie il CuSO4 mentre nell'acetilene si scioglie? lo iodio. centra qualcosa polare e apolare , ho sentito che lo disse la prof!!!!11

My polarizer is now in three pieces. I just came apart in the field and the wire o-ring came out. Can I get this back together? I have tried to put it back with no success, I was hoping to get a tip from someone here if it had happened to them
I don't...

I have.
Not sure if the solvent in the thread lock would bother the pol film (even just gassing off).

I recently bought a polarizing condenser for my Orthoplan, but the
polarizing filter won't rotate. I applied some xylol into the gap where it
should rotate but the only effect was...

If grease is the problem, then you need a non-polar solvent, not the polar
ones you're considering;gr...@planet.nl
Theo,
I would wrap the unit in Kim-wipes or something similar and use a
solvent death to be boring.

I have both the Klein and McMurry Organic Chemistry textbooks.
Klein says that nucleophilic strength increases DOWN a group in a polar protic solvent and increases UP a group in a polar aprotic solvent. So, Klein is essentially saying that a smaller nucleophile...

Answer Snippets (Read the full thread at chemicalforums):
So your original question, which mentions polar aprotic versus polar protic solvents, really.
For a short answer right now, but the solvent can have large effects on both basicity and nucleophilicity.
