Polar and non-polar compounds and their solubility

AI Thread Summary
Naphthalene's solubility in liquid ammonia, despite its non-polar nature, raises questions due to ammonia's polar characteristics. The discussion highlights the unexpected solubility of naphthalene in liquid ammonia, which contradicts typical solubility rules. The inquiry stems from research focused on naphthalene carry-over in gas systems, where literature indicates that naphthalene can dissolve in liquid ammonia, prompting further exploration into the underlying chemical interactions or reactions that facilitate this solubility.

TL;DR Summary
Hydrocarbon Solubility in Polar solutions
Hi
Please can anyone explain why Naphthalene is soluble in liquid Ammonia when Naphthalene is Non-polar and Ammonia is Polar?

Good question. I would expect the solubility to be very low. Where does your question come from? Is this related to some chemical reaction or rather spectroscopy?

Hi DrDu, thanks for your response.
The question comes from research into modes of Naphthalene carry-over in gas systems.
I was surprised when I was faced with articles stating Naphthalene to be soluble in Liquid Ammonia.
 

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...

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!!
