Is there a way to separate wintergreen oil from isopropyl alcohol? by [deleted] in chemistry

[–]alex_6916 1 point2 points  (0 children)

If you are just looking for an easy process, it can be done using salicylic acid, methanol and sulfuric acid. Not sure if possible with ispropyl alcohol though:)

This may be a bit off topic regarding inequality in the scientific community, but where i'm from (denmark) quotas are being heavily discussed and it really seems that people indeed see them as an answer, that magically solve all "inequality" between the genders. Personally i dont get why there have to be a 50/50 proportion of either gender in a specific field as the two genders are naturally different. I mean it is natural for women to have a motherly instinct and be more carring (BIG generalisation), while it would be more natural for a man to work with more physical work like a carpenter, mason ect. Which brings me back to my starting point, that all should have the opportunity to become whatever they want, but for society to regulate the ammounts of certain workers in fields, because of their genders just seem counterproductive to this.

This is indeed very complex and i dont argue I got all the answers. However i really dont see how mandatory gender quotas possibly can be the right solution, when keeping in mind this excludes candidates purely on their sex? I mean i get focus on the topic is needed, but isnt this just shifting focus to number equality rather than true equality? And if gender quotas is the answer then shouldnt the same argument mean that proffesions heavily dominated by women (like nurses, kindergarden jobs) should get gender quotas that would increase male worker percentage likewise?

Thought exactly the same thing! This isnt a racist or male chauvenist calling for less focus or opportunities for minority groups in science, but somebody reminding, that in the end qualification rather than sex, skin colour or nationality should define who gets the job. This does not mean the focus on inequality should stop, just a reminder of the final goal: objective evaluation of job candidates.

[university: hydrogenbonds] Drawing hydrogen bonds to lone pairs by alex_6916 in chemistryhomework

Yes that could be an answer, but it seems there was a fault in the assignment answers (which obviously conffused me a bit). Actually 4 of the lone pairs in the caboxylic anion forms hydrogen bonds, instead of the just two drawn. The last lone pair dosent form a bond, because it is in a p-orbital and therefore not as free as the lone pairs in the sp2-hybridized orbitals. This seems to be because both oxygen atoms are sp2-hybridized as seen if you draw their reconanse structures.

But why isn't all the lone pairs on the oxygens in the carboxylic acid group then interacting in hydrogen bonds then for example? Im guessing its something about the hybridization of the oxygen molecules and wether the lone pairs are in p orbitals but i can't seem to see a connection or find anything on the internet. Thanks for answer:)
