The discussion centers on the nomenclature of isopropyl in IUPAC terms. It questions whether isopropyl can be correctly named as 1-methylethyl, emphasizing that isopropyl is essentially propane bonded to another group at its second carbon. The conversation highlights that isopropyl alcohol is equivalent to 2-propanol, reinforcing the idea that propane should not be referred to as 1-methylethane. The participants argue that propane is a simple n-alkane and that using alternative names like 1-methylethyl complicates the straightforward naming conventions established in organic chemistry.

I was wondering if it's correct to name isopropyl in IUPAC as
1-methylethyl?
There are no structural isomers of propane itself. By itself, isopropyl is nothing really--->just the same ol' n-propane. Isopropyl bonded as an alkyl group to something else is really just propane bonded to that something else via its second carbon (carbon #2). For example, that's why we say "isopropyl alcohol" as equivalent to "2-propanol". (or isopropanol)
As for the nomenclature, why would you name propane as 1-methylethane ? Propane itself can only exist as an n-alkane. Ethylethane is n-butane, but we just say n-butane.
Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.
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!!
