    Phenol
AI Thread Summary
Phenol reacts with FeCl3 to produce a violet coloration, indicating its presence. 4-methylphenol is also expected to give a similar violet coloration due to its phenolic nature. The discussion clarifies that the FeCl3 test is specific for phenols, allowing for differentiation between phenols and carboxylic acids, such as 4-methylbenzoic acid, which will not produce the same reaction. This test is useful in distinguishing between these compounds in a laboratory setting.

phenol + FeCl3..help!

:confused: :confused: please help me... :frown:
phenol gives a violet coloration when we add FeCl3, but will 4-methylphenol gives a violet coloration?!? :confused:
n is it possible to distinguish 4-methylbenzoic acid from 4-methylphenol by adding FeCl3? :confused:
sorry for my poor english :-p

The test is fairly specific for phenols, thus I'm thinking that the methyl phenol will also test positive; not all phenols test positive however. Yes, this test will distinguish between phenols and acids.

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!!
