Symmetry, absorbtion and benzene

AI Thread Summary
High symmetry molecules generally have lower light absorption compared to low symmetry molecules. This is illustrated by comparing benzene, which has high symmetry, to benzene with a hydroxyl group, which introduces asymmetry. The presence of a functional group can affect light absorption, as symmetric attachments may have a reduced influence on the electric dipole, impacting the molecule's ability to interact with light.

Hey
Is it right that high symmetry molecules does not absorb light as good as low symmetry molecules? let's take an example like benzene versus benzene+hydroxyl?

Depends on which atom or functional group you're are referring to ; if it's the same functional group I would imagine that a symmetric attachment would be less of an influence with an electric dipole .
 

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!!
