21.3 Isomers in Coordination Chemistry | General Chemistry
HTML-код

- Chad provides a comprehensive lesson on Isomers in Coordination Chemistry. First, the difference between Structural Isomers and Stereoisomers is explained. Then the two types of structural isomers are presented: Linkage Isomers and Coordination Sphere Isomers. The Coordination Sphere Isomers included both Ionization Isomers and Hydration Isomers and examples of each are provided.
Then the two types of Stereoisomers are discussed: Geometric Isomers (Cis/Trans Isomers) and Optical Isomers. Geometric Isomers are possible in both square planar and octahedral complexes and it is explained what must be true of a coordination compound to be capable of Geometric Isomerism.
Finally, the lesson is concluded with a discussion of Optical Isomers. A complex ion is said to be 'chiral' if it and its mirror image are nonsuperimposable (i.e. nonidentical). The two nonsuperimposable mirror images are not only stereoisomers, but more specifically optical isomers and 'enantiomers.' Optical isomers occur most notable in three different complex ions:
1. Tetrahedral complexes with 4 different ligands
2. Octahedral complexes with 3 bidentate ligands
3. Octahedral complexes with 2 bidentate ligands and 2 monodentate ligands in the cis-conformation
Examples of each are provided and discussed.
I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at www.chadsprep.com/chads-gener...

Despite being labeled as "low yield" by companies like Kaplan, coordination chemistry shows up a lot on the MCAT. It's good that you're covering it in depth.
Indeed!
Hey Chad, greatly appreciate all the hard work you put into these videos. I'm nearing the end of my second semester of general chemistry and your uploads have perfectly aligned with my class work. I know you have Organic Chemistry playlist, but I was wondering what you'll be uploading after this ends. Thanks again!
Thank you so much, the way you explained cis/trans made it so much easier to understand! I’ll be watching all of your videos in your chemistry playlist and I can’t wait to learn more!!! :)
You're welcome - Happy Studying!
Hi Chad! thank you so much for the video. i had one question, for the trans isomer at 10:32, why is also not a cis isomer as OH2 is 90 degress from OH2 and as H20 is 90 degrees from H2O? I'm in a class where we are not covering this in depth, but I am still curious. Thank you for the videos, they help me a lot!
Thank you Chad for making it look easy, i struggled to learn in the class but didn't make it, but thanks to you I am able to teach my friends
Glad it helped and good job for helping others!
You speak so eloquently and clearly, thank you so much God bless you!!!!!
You're welcome and Thank You!
One question Chad, for the octahedral complexes, you mention that you need 3 bidentate ligands to make optical isomers. Do they need to be the same exact ligand, or can they differ and still form optical isomers as long as there are 3?
In our textbook instead of drawing actual structure of [en], they have shown wings of a butterfly (like in children's book) for simplicity.
Im in advanced inorganic chem and this was definitely a needed review! Thanks :)
Glad the channel is helping you - Happy Studying!
thanks for saving my grade two years later! you really do go into detail
Glad it helped!
Thank you Chad, you're the best teacher on YT!!!
You're welcome and Thank You!
thanks for the video but i have one question. so you state that bc. of the two chlorines the platin complex is either cis or trans.... isnt in due to the bromine and iodine bc. i thought you have to use cahn ingold prelog right?
hi chad do you have a vieo on how to draw a Hess cycle
I just wanna say THANK YOU SIR!!❤❤ you are just amazing
You're welcome and Thank you!
Tomorrow i have report on theme " Isomerism in Coordination Chemistry " and I've found your video helpful. Thanks for good exploration ❤❤❤❤. Respect your jod
Glad the channel/video is helping you.
Thank you for your videos, Chad! They’ve helped me so much this semester and I don’t think I could pass without you #ChemDaddy
Glad to hear this and happy studying :)
I have a question! at 10:47 why did we look at Cl atoms to determine if it is cis or trans? Because if we look at H20 they can also be trans and cis. Is there sth like being both cis and trans for the same molecule? Thank you for the lectures, they are really helpful!
20:30 sir for this type of complexes to be optical isomers should the bidentates need to be identical
best explaination I've had with optical isomerism
Thank you for saying so.
Thanks a lot, sir!
Most welcome!
thank you! this video literally saved me
You're welcome - glad you survived to study another day!
thanks , it was very helpful ❤️❤️
Excellent!
thank you so much for the help!!!
You're very welcome.
Super helpful 10/10!
Glad it helped!
Thank you!!
You're welcome.
Thank you so much.
Very welcome.
Thank you so much
You're welcome
Very welcome
Thank you 😊
You bet!
I was starting to think I was stupid because I couldn't see all these in 3D. Thanks, you explain very well
You're welcome and Thank You.
thank you for this sir
You're welcome!
@@ChadsPrep you inspired me a lot to be a chemist and professor soon. hopefully i could meet you someday. 😍thanks for the videos
Best❤
Thank You!
intriguing
Welcome to the channel.
What a chad
Welcome to the channel
the last joke doesn't deserve such a chad
Indeed!
@@ChadsPrep can we expect reaction machanism of coordinate complexes
Nice sir!
Thanks!
Sir without giving examples for what you are discussing will be hard to imagine and understand and I wonder if you slow down your talking. I
