Max Yield Phenolate Formation with Phenol

AI Thread Summary
Phenol forms phenolate with maximum yield under high pH conditions, as it is a weak acid. To achieve this, adding an excess of a strong base is essential. While sodium or potassium hydroxide is commonly used, employing sodium hydride as a stronger base can enhance the reaction, particularly in tetrahydrofuran at temperatures below 10°C. This controlled approach allows for optimal phenolate formation.

under what circumstances phenol forms phenolate with max yield
 
Chemistry news on Phys.org
High pH - it is a weak acid.
 
I know it's a weak acid. I need to know circumstances of forming phenolate with max yield
 
High pH - add excess strong base.
 
I agree. If you are seeking extremes, you might want to add sodium hydride (a very strong base, not needed to prepare phenolate) instead of the commonly used sodium or potassium hydroxide in tetrahydrofuran under 10°C in a controlled manner.
 
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...
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!!
