I had to momentarily pause the video midway to say, I think this lecture, and many in the series have saved my chemistry degree. My teachers are just useless at explaining this content in tutorials and in the written content it's even worse! Why do uni's insist on over-complicating things to the point where you become disheartened? I truly thought I was too dumb to comprehend this topic, now I'm just irritated that it took me so long to find a really good explanation, but I'm also really motivated about the rest of the course. Thank you, Catherine.
Yeah, that's often the key to understanding any topic. For a person with normal intelligence there's not topic that can't be understood. So if you don't understand something it's usually just not explained very well in terms of the knowledge your already posess. So you just need to find people, books, websites etc. that explain in a way that you understand.
This video is extremely clear and includes example questions to check your understanding periodically. Highly recommend this video to all those either looking to learn or review this topic
this video basically exposed the fact that other chem professors dont know what tf theyre doing. this is how you teach a class and demonstrate abstract theories. not a single instance of reading off the slide, so 100 catherine i love u
I saw one of her classes from 11 years back MIT just now and this one followed... still the quality of education being imparted is priceless.. thank you Maam.
Well in my University it takes one quick and condensed lecture and you go home with barely the title in your mind - "It is not needed to know these stuff for any job - only for "teaching" it to students to pass the examination". Loved the lecture very much, thank you for sharing!
Wow this is so much easier to understand than my chem lectures...plus a lot more fun to listen to...wish teachers could all be this clear and interesting!
I would like to say that this lecture is stunning and amazing. I really enjoyed every part of the lecture, it was clear, the examples are just great. Thank you Pr. Drennan. The fruit of Pr. Ludwig is in front of you.
Shouldn't the deexcitation of electrons produce back the green color (500 nm) while all the other colors in the visible range being absorbed for incomplete excitation of the electrons? You know, like the atomic absorption spectroscopy (AAS) principle. 50:00

hello! if u count in the periodic table the number of groups from the metal (ie grp 1) until Fe, Fe would be under 'group 8'. to find the count, u take the group no (so 8) - the oxidation number, 3(u can ignore the +/- sign) which gives u 5.
stabilizing energy is different from splitting energy. You need splitting energy to split those d orbitals. The fact that CFSE is 0 is just attributed to the relative stability of the t2g and eg.
One thing that many of our course videos are missing are the recitations. Many courses have recitation sessions where students are welcome to ask questions on anything they are confused on. For example, 5.111 recitations met 2 times per week for 1 hour per session; 26 sessions total; mandatory attendance. For more information, visit ocw.mit.edu/5-111F14. Best wishes on your studies!
Many energy differences such as those between orbitals, states, etc. are called "delta". This is a course that is defining this particular "delta" for the first time and it makes sense to say "octahedral crystal field splitting energy" multiple times. This isn't a graduate level inorganic course.

Cal professors love to overcomplicate chem

BLESS THIS WOMAN, ive been looking everywhere for proper explanation of this topic, finally found it, thank you :)
Same here after 2 years
See physics wallah video

She amazing teacher and always uses humor way to fully explain the difficult chemistry rules
the best chemistry teacher so far, thank God i came across this masterpiece
15:20- "energy conserved" making the understanding of the splitting energy easier 👍
39:05- so, that means PE
Only these lectures can give the real feelings of chemistry
I love this type lectures
Really thanks for your clear explanations. I learned a lot to explain my quantum mechanics calculation results.
Most insightful video on Crystal Field Splitting Energy/ Possible applications. Merci Beaucoup.

thanks for the lesson I've learnt a lot, i wish that one day i will come to MIT🙂
This was awesome - loved the teaching , clarity and 16:36 was the best
This is so beautiful!!! Chemistry is so much fun and interesting!
Thanks for amazing explanation this really helped my research 🎉
This lady is a breath of fresh air in the dullest education institution, ie university.
This is clearly the difference between an MIT class and a class from my University (im from Uruguay and I understood this just perfectly!) thanks
You are great at what you do! Great teacher!
excellent lecture...
Extremely understandable. Thanks
One of my favorite Madam,
Thanks
Such an impressive lecturer!
This is so good and clearly understand than my university lecture, was searching this topic to clear my mind before exams,
thank you
And here I have to deal with this in better details right in class 12. #StrugglesInCBSE
😂😂😂
Doing this at Class 11 . #strugglesInHSC
Wow, that woman and the way she teaches is amazing 👌👌👌
Wow, this all makes sense now! Thanks so much!
Great .....Really Incredible....I wish to have such awesome classes..
Completely understand each and every topics thanks 🙏
oh MY GOD THIS IS FREE????!!!!?
Loved this excellent teaching.
All it takes is willing interestedness of a teacher to teach

Amazing clarity
you are amazing i wish you were our professor
Thank you Prof.!
Very well explained 👍
THANK YOU SO MUCH
Mam just awesome.you have cleared my confusion. Love you from Bangladesh 🇧🇩🇧🇩
Adamjee Cantonment College
I loved this class
we wonna thank mit for their magic justification and we need courses about teaching
awesome lectures
The topic is so well explained :)
Simple theory can explained alot
Her T shirts are just ❤.
Very Informative video , Thanks .
Amazing lecturer.
She is awesome
Excellent lecture!! But I had to pause for a while 'cause of that 'ah' in 16:35 lol
Thanks for the lecture, you made me seek out my copy of Jolly's modern inorganic chemistry book. It looks like I've actually read it :-)
a lot of thinks from my heart doctor💜💜
I'm sure it's a stupid question, but octahedral means 6 bonds and we have FIVE d orbitals. So where exactly are the electrons from the ligand going?
Thanks ma'am
Thank you soooooooo...(o x 42) much!
Awesome thanks
Thanks alot

How does the 6th ligand coordinate? Does it fill an empty p orbital?
Where do I find the other parts?

@@mitocw Thank You very much!
Hi, everybody. Why, at the minute 20:34, she got 5 for the d count? From where the 8 cames? Thank you.
hello!
if u count in the periodic table the number of groups from the metal (ie grp 1) until Fe, Fe would be under 'group 8'.
to find the count, u take the group no (so 8) - the oxidation number, 3(u can ignore the +/- sign) which gives u 5.
THANK YOUUUUUUUUUU
IN CFSE the value is 0 in the case of fe(h2o)6 ,so why would they split into two different categories of energies as t2g and eg
Chakradar reddy -100 +100 =0
stabilizing energy is different from splitting energy. You need splitting energy to split those d orbitals. The fact that CFSE is 0 is just attributed to the relative stability of the t2g and eg.
Does MIT not have the culture of asking doubts by raising hands while the teacher has paused, or is everyone smart enough to understand it completely?

We study these in High School in India. 😁
Haa, bhai. IISc main bhi padhte hai ye cheeze
Why u still lagging then?
Lol, everybody in comment section seems to be from university, I am in 12th grade, watching this
👌
Okay but seriously thank you 🙏🏿🙏🏿🙏🏿 My prof can't teach whatsoever 😭
See this link 38 seconds only for chemistry
"octahedral crystal field splitting energy" when you could just say "delta"

Somebody notice her t shirt it's pretty cool
And there is me... studying more deeply than them in class 12 for jee advanced 😭😭😭😭
I tell bad chemistry jokes because all the good jokes *Ar*
رهيب❤️🥹😍
Notice her t shirt.
She reminds me of velma once she had to retire from the mystery gang
A level student here hahahaa
where can i get the notes mentioned in the lecture if its possible?
