Riddle me this batman!! if cis and trans are just terms made up by the wokes and isn’t real biology, then why are they in my biology textbook

Okay. so. I need all my crafty friends to check out my favorite new indie yarn company.  Check out the fun colors and stripes and everything is fun science themed!

This one is called Scopolamine, its my favorite but there are other great ones too and you can sort it by which isomers are your favorite!
This one is called Fumaric acid or trans-butenedioic acid and some portions go to a charity for trans folk which is really cool and nifty

The designer also has a bunch of really cute yarn markers and some really cool 3d printed yarn boxes.   Go support this really cool yarn artist!!  (and maybe tell them stupidebeecandle sentcha :p )

Hello! This is my blog dedicated to my studies! I’ve always wanted to have a study notes blog and I’ve always been so inspired by the other study blogs.
I intend to post my notes, my to-dos and maybe share some of my tricks I use for studying.
I’m excited to share my Review of Isomerism from my book notes for Organic Chemistry I.
Happy studying!(๑>◡<๑)

Using a manganese polymer to separate xylene isomers
A team of researchers at Zhejiang University in China, working with colleagues at Rutgers University in the U.S., has developed a way to use a manganese polymer to separate xylene isomers. In their paper published in the journal Science, the group describes the process and notes that it is simpler and less expensive than other methods.
Xylene isomers are important chemical intermediates that are often used to make different types of plastics. Three of them are of particular value: par, meta and ortho. Unfortunately, as they are synthesized in standard processes, they come out bound together. In order to be useful, they must be separated. But doing so has proven to be time-consuming and expensive. This is because all three have similar structures and boiling points.
The work by the researchers involved finding a material that could serve as an adsorber—where molecules of a liquid or gas form a thin film on a surface that can then be collected. They searched for one-dimensional coordination porous polymers that were known to have flexibility and identified manganese, which initially seemed as if it would not work because its pores are too small. But the researchers found that when exposed to a xylene mixture, its structure swelled, increasing the distance between the polymer chains and making the pores bigger. And that allowed for adsorption and consequent separation of the isomers.

In this more advanced version of the machine (figure 23.9), the -CH2-CH2- linking the phenyl ring to the cyclodextrin was converted to an alkene, and this serves as a photochemical on/off switch.

Firstly, 4-methylcyclohexanol can exist as two stereoisomers – a pair of cis-trans isomers. Both the cis and trans isomers are meso compounds and are achiral.

Lactic acid
Lactic Acid, a group of stereoisomers.
Fun fact, this stuff can accumulate in your muscles when you work out.

I’ve been on spring break recently, so there wasn’t much to post.
Studying for my second exam, and I’m really struggling with enantiomers and meso compounds. Any tips? I feel like I’ve watched every video on the subject.
