21.1 Introduction to Coordination Chemistry | General Chemistry

Chad provides an introduction to Coordination Chemistry in this lesson. The topic revolves around the coordinate covalent bond which is formed between a central metal ion acting as a Lewis acid and one or more ligands acting as Lewis bases in the formation of what are called complex ions and coordination compounds. A list of the most common ligands is presented. The coordination number is the number of bonds made to the central metal ion, and the most common coordination numbers of 2, 4 and 6 are discussed. For a coordination number of 2 the geometry is linear. For a coordination number of 4 there are two possible geometries: square planar and tetrahedral. For a coordination number of 6 the geometry is octahedral. Polydentate ligands are also discussed which can form more than one bond to a central metal ion. They are also commonly referred to as chelating agents, and complexes formed between metal ions and polydentate ligands are often referred to as metal chelates.

Using this to study for my inorganic chemistry final - this is going to be a life saver.

[@ChadsPrep]

Hope you do well on your final - Happy Studying!

[@ezioauditore4109]

Very nice, Chad. I might actually pass tomorrow's test.

[@ChadsPrep]

Thanks - I hope you do well.

Hi Chad! I finally got into dental school (I used your studies) and now I'm taking chemistry in dental school and I am still watching your videos to review and learn things I forgot overtime. I thank you with all my heart!

[@ChadsPrep]

Congratulations Hazel! I hope you had a little bit a time to just feel good about where you've gotten, before getting after it again!😊 Best wishes to you in dental school and beyond!

[@rahhulelangovan]

Your voice is actually so soothing! Helped me study so much!

[@ChadsPrep]

Glad it is - Happy Studying!

[@cynr6406]

Do you happen to have a video on 18 electron rule with the ionic method and covalent method?

[@KomalParmar3112]

You made inorganic interesting to me....thank you very much

[@ChadsPrep]

Most welcome!

[@delbago5461]

In organic, some reactions halpen bc an anion donates 2 electrons to form a bond (e.i. saponification, OH donates a lone pair to the pi * system), is that also a coordinate compound?

[@yousrasalihsalihabdalla8418]

this was extremely useful 🤸🏽🤸🏽

[@ChadsPrep]

Excellent!

[@patreeshanakato-ux6el]

your lectures are so good

[@ChadsPrep]

Thanks for saying so - Happy Studying!

[@irem9955]

loved it!

[@ChadsPrep]

Excellent!

[@fallzexe2569]

thx u helped me alot on my tests

[@ChadsPrep]

Glad to hear that!

[@ItsMe-dj6pl]

Perfect 💛

[@ChadsPrep]

Thank you :)

[@hafizali6278]

Really helpful 👍

[@ChadsPrep]

Excellent!

[@loygebaguio6468]

Good day sir, i watched you a lot. could you upload more in coordination chemistry. Like structural and optical isomerism

[@ChadsPrep]

Several more lessons on this chapter coming throughout the week. Naming complex ions/coordination compounds later this morning and a detailed lesson on isomers tomorrow! Hope this helps!

[@BadassVideos]

what's the charge on the Fe in [Fe(H2O)5 Cl] Cl2, is it Iron +2 or Fe +3 ?

[@ChadsPrep]

+3 to balance out the Cl ligand and the 2 Cl counter ions. 😊

[@bayareacgn]

Thank you for all your helpful videos. I think that in the formula of EDTA 4 C atoms are missing...

[@ChadsPrep]

You're welcome :) is this in the chart around 10mins?

[@SAMTV5623]

Why do we have 2+

[@EndTimeVoice1]

God bless u

[@ChadsPrep]

Thank you - to you as well.

[@RelaxRailRide]

Nice sir! You looking is too young

[@ChadsPrep]

Thanks!

[@odukogbeolutola6699]

Speak slowly you are teaching some Africans.We can't understand you sir.If you can speak slowly many of us will always view your video and subscribe.

[@ChadsPrep]

You can change the playback speed under the settings to something more manageable. Happy Studying!

[@tanseltopal5355]

You are talking so fast

[@ChadsPrep]

I get that a lot - you can change the playback speed in the settings. Hope that helps.

[@tanseltopal5355]

@@ChadsPrep thank u❤

Happy Studying!
