Understanding the Naming Conventions of Epoxides: R and S Omission Explained

AI Thread Summary
The discussion centers around the naming conventions of epoxides and the omission of R and S stereochemical descriptors. It highlights the potential confusion that arises when both CH groups are positioned on the backside, leading to the possibility of different molecules sharing the same name. The conversation suggests that the drawing may represent a racemic mixture of cis isomers, which could explain the lack of specific stereochemical notation in the name. This raises important questions about clarity and precision in chemical nomenclature.

for this epoxide, I don't understand why the R and S part are omitted from the name?? If both of the CH groups were on the back side, it would be a different molecule, yet have the same name??

As discussed at chemicalforums, it's possible that the drawing is meant to represent a racemic mixture of cis isomers.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

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!!

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
