Heck, Edward, you left the butter out of the fridge all weekend. It was rancid.
Sorry, I left late on Friday, I forgot.
So that was what was with that awful stench?
Do not exaggerate, go. I already apologized. And look, the smell of nail polish is not that great.
Hey, guys? Speak, Joel! Arriving at the shop? No, my car came in today.
Hi, guys. I’m Clara, Belem, and I am with a question.
I have to do a group work to school, my part is about isomerism.
Can anyone help me? Where did this term “isomer”?
What is? E isomer space? Does anyone know what it is?
Write here, Eduardo. Isomerism – Greek iso, equal, and mere parts.
Occurs when two different compounds have the same molecular formula.
And now? Where do we get an example of isomerism?!
a solvent found in nail polish formulation that Luiza is using.
The isomers are out there, everywhere.
If the atoms present in the compound isomers are the same, what changes?
Change the arrangement of atoms in molecules.
Let me give an example. You two, get your stuff and put on the bench.
Why? Go ahead, I’ll show the difference.
See? The elements are the same, but you got one way and another Luiza.
What changes is the arrangement. This structural arrangement is the plan or simply flat isomerism.
Well, I understand the theory.
And the other kind of arrangement? The spatial arrangement of atoms.
This other type of arrangement can call only spatial isomerism. Let me see how to explain.
Look at those two chairs. They are equal, are not they? Are.
If you overlap one another, you can see that the spatial arrangement of them is different.
The claws were on opposite sides.
Look, we have these two molecules, derived from but-2-ene.
Dividing these molecules in two planes separated by the dotted line,
While in these same molecule two groups are in opposite planes.
That alone is sufficient for the two molecules have different physical properties.
And how do I distinguish the two?
Thus, we have the cis-but-2-ene and trans-but-2-ene.
If we put on the cis isomer, the molecules will not match.
In medicine! The spatial isomerism is of great importance in the efficiency of remedies.
Look Luiza, the photos I took.
You took a picture of yourself in the bathroom mirror, Eduardo, what an idea!
Gee, is he an isomer of itself?
Today we learned that the isomerism is: when different compounds have the same molecular formula.
And we found the application of the isomers in medicine and in day-to-day.
