Crystal Field Theory

We are used to using a theory like VSEPR theory to predict molecular geometry, but unfortunately with coordination compounds, things are not so simple, because of those pesky d orbitals on the central metal atom. Crystal field theory is a model that is quite successful in predicting the geometries of these compounds, as well as other characteristics, like magnetic behavior, and color, so let's learn about this theory now!

Carry on Sir. In a very short time, you always make the toughest the easiest one. Your lessons always inspire me. When I search any topics on RUclips & your tutorial appears before me, I became very excited to see yours 1stly. 😎 Take a bow 😍

[@sim6281]

Why can't we have professors like you in class???

[@ahsanhabib7502]

Gobble

[@ramlaaal]

because there is a big difference between passion and profession.

[@pranavbansal5440]

Coz he is hard to find

[@lyricsbooth802]

Cause they can't afford

[@SOUL.2006]

This topic is taught to what grade student -schooling or college or other ???

[@PleasanceLiddle]

You're the best, man. I've been watching your chem videos for 2 years now. I'm in my 4th semester of chem and I always watch your videos late at night just before an exam and I always get A's. You're a rockstar and I'm diggin' the new(ish) haircut, it's cute!

[@designingworld5306]

I too are in 4 semester

[@ЭйвейлАлександр]

He is your saver LOL

[@PleasanceLiddle]

Heyoooo I'm in PT school now, holla!

[@shreyamurali1934]

I literally have a chemistry exam tomorrow on this and this is going to save my grades ! Thank you for this short and simple, but effective explanation !

[@ujjwal8549]

Same this brother 👍

[@TheAnnie121]

Taking my Inorganic chem exam in 3 weeks, needed this so badly! Thank you so much for keeping uploading videos during the summer. Greetings from Czech Rep.!

[@lakhveer0362]

😣

[@anthonymangiaracina1163]

Thank you for this. It's difficult to find help with inorganic chemistry concepts online, so I appreciate it getting some attention!

[@shlokekhullar4261]

Sir u just taught the topic which I had been struggling with for 7 months in just 7 minutes ....it was just magical....all my concepts are clear now...thank you soo much!!

[@yahayamusa264]

A very good explanation sir, you are a solution to my problems in chemistry thanks for the video

[@mugdhawadhavekar4515]

Two words- Explained Awesomely.
Thankk Professor Dave!

[@madhvivarshney169]

Sir we didn't have professors like u .u explained very clearly which will help me in my exams thank u sir 😊😊😊😊

[@yourebreakingmyballs4787]

A 1 hour lecture explained in 7 minutes. Thank you very much, Professor!

[@TheScienceBiome]

Boom, and just like that I understand the electrochemical series. Serious props to you!

[@its_me_999]

Thankyou Professor LOVE FROM 🇮🇳

[@jeffreysayed8621]

I like your explanations. They are brief and concise. I have a background in Chemistry. When it comes to ligands, do we not have pi acceptor and pi donor ligands? If you do not have a video on that could you do one? Also do you have something on the spectrochemical series?

[@englishwithoutstress3749]

Professor Dave, you're the GOAT. Your lessons are clear as day. Thank you so much for breaking down tricky subjects like this. I owe you one. Have a blessed week!

[@headmanlesetlhe1635]

Magnificent, splendid you explain an hour lecture in just under 8 min... you're the best

[@viviananica3775]

Thanks! Great timing, just went over this in summer class.

[@kchathurangamusic]

explaination very clear ,short and sweety ,thank you very much sir

[@Benneification]

So why exactly do the ligands repel these orbitals making them energetically unfavorable while in classic bond theory we explain the formation of a chemical bond by OVERLAPPING orbitals?

[@HarshSingh-ii6jm]

from india class 12th

[@Nishad7800]

Same here

[@nayanika9277]

Thank you so much Sir. This was very much benificial.

[@angelphalane399]

Thank you Prof!

[@666Jade1]

So strange to see you with short hair! Thank you for all your videos. I also loved your Italian tutorials :)

[@samreenaziz8383]

You're absolutely explaining it well.

[@virajvakharia6759]

Great teaching 👍 carry on the good work

[@aahiljcat]

Oh great this gets recommended after my final chemistry test. Thanks youtube

[@isakhan3252]

Wait a minute. What happened to your iconic hair???

[@MillyC9922]

Hi, I absolutely love your videos, they have already helped me a lot throughout my undergrad degree, so thanks a lot!! Just one question, at 5:16 in your diagram for square planar complexes, shouldn’t the dz2 orbital be lower in energy than the dxy orbital?

[@santbhindranwalejidefanche8767]

Yes it should be. In order of highest to lowest:
(dx2-y2) > (dxy) > (dz2) > (dxz, dyz)

[@heirta21]

This is so good. Thanks a lot!

[@justinfrank3552]

Can you explain when two more more different ligands are coordinated and how these affects the high spin and low spin complexity

[@boniphancebunzali5668]

Sir, I understand u very well, thank you from 🇹🇿

[@idreesahmed9788]

Thanks sir I got your all points but cofused in axis of d orbitals

[@gavgaff]

I remember it by the exponent meaning on the axis (e.g. x^2 - y^2 means the orbitals are on the x and y axis, and z^2 meaning the orbitals are on the z axis) and for the orbitals that are in between the axis, the notation tells you which axis they are between (e.g. xz means the orbital lies between the x and z axis, yz means the orbital lies between the y and z axis, and xy means the orbital lies between the x and y axis). Hope that helps!

[@venkatachalapathivv4528]

Thank you!

[@fatemehyavari3807]

Thank you so much.

[@abeerurfan2743]

thank you so much 🌸

[@spuddsalli8559]

So weak field ligands show less colour and strong filled ligands show more colour as the difference in energies is sfl is greater than wfl, right?

[@NHenry-dy2fo]

This is a great one.

[@lakshmidevibemplassery2067]

It is a very good video

[@readytolearn77]

Thanks a lot

what are your thoughts on starlight and the African donut stone using sound magnetism to produce electricity?

[@the_geminiestic]

Can you also make a video on Ligand Field theory???

This is awesomeee!

[@botchalavanya8712]

What is the CFSE value of co(NH3)6+3

[@meherkhan1467]

Thanku professor

[@imanramadan1227]

Thanks

[@benYaakov]

Hello , I have seen on internet that shape of dz² is square planar . Is it correct ? And what do it mean even ?

[@ProfessorDaveExplains]

no there are no two-dimensional orbitals, check out my tutorial on quantum numbers for the orbital shapes

[@benYaakov]

@@ProfessorDaveExplains ok , thank you

[@PritomAhad]

At 4:54, it ligands approach dxy dxz dyz, so it means in tetrahedral higher energy shells get filled first? But in octahedral the lower shell got filled?

[@ProfessorDaveExplains]

So it's always the lower-energy orbitals that get filled first, it's just that the identity of the lower-energy orbitals changes depending on the geometry.
