Look here! TH-cam is deleting all annotations, which I have used in the past to make corrections, so I want to make sure everyone knows that at 0:16, 1:58, 2:12, and 2:40, I say "molecular orbitals" but I meant "hybrid atomic orbitals". Also, for the molecular orbital diagram for N2, the pi 2p bonding orbitals should be below the sigma 2p bonding orbital due to s-p mixing. These are major errors so please make the correction in your head, sorry! I've been much more careful about triple checking my work since these early videos, I promise. UPDATE! This new video about MO theory is much clearer, please watch the new one immediately after this one to get some clarity: th-cam.com/video/I2k61JMk71M/w-d-xo.html
Thanks for great explanation and care for delivering accurate information . But I have an enquiry about molecular orbitals ... Molecular orbital theory assumes that number of atomic orbitals = number of molecular orbitals , for example in case of formation of H2 molecule there is two atomic orbitals that formed one molecular orbital ( the bonding orbital) , but I can not understand how the other(anti bonding ) orbital is formed .. can you explain it please !
Check out my classical physics tutorials on wave mechanics, the bonding orbital is the result of constructive interference and the antibonding is the result of destructive interference!
bro every single unit in highschool no matter what AP i always understood after watching a vid orgo chem tutor or prof dave. Never in my life have I expected something to be so confused I wouldnt even get it after asking a chem national winner and a yt vid. If you understand how the antibonding thing works for H2 please lemme know. I get it if there are 2 electrons from each like 1s2... sure one from each go to the sigma and "sigma star" whatever that is. But with h2 there are ONLY 2 ELECTRONS. HOW TF DO YOU FORM 2 DIFFERENT ORBITALS??? is this schrodinger's cat??????
@@derek7566the orbital isn’t necessarily a physical thing that’s formed it’s just a new area to describe where electrons will be found if they’re antibonding
I used to have an average of 70-80 percent on chem tests. I watched your series for the last test unit (vespr/bonds/shapes/etc..) and got a 98.6%. I couldn't thank you enough for your precise, easy to understand videos. Real heroes don't always wear capes, just beards.
@@ProfessorDaveExplains Absolutely awesome videos !! Though I'm still at junior highschool, It's easy for me to understand these collage stuffs after watching your video. Thanks for uploading so many nice videos !!!
Khan Academy's video on sp3 and sp2 orbitals greatly helped me understand the content covered in this tutorial. This tutorial is more of a refresher to solidify your knowledge, so I would definitely recommend watching Khan Academy's video before this one.

You are literally a life saver...I have had multiple breakdowns over this material and was able to learn it in 7 minutes. It seems like it's actually super easy!! Thank you, Professor Dave (you're my hero)!
It's amazing that Professor Dave explains this in 7 minutes and gets me understood while my professor discussed mo for 20 minutes and still confused half of class.
@@spiral8138 Ya you are right. I'm not forced to major in the field I want to work in. I can do something else. I hate when people like you use semantics like that. Truth is, I only took chemistry because my department forced all students to take general ed chemistry. It has nothing to do with rounding out our knowledge. It is, in every way, pointless information for this field. It's just another way to milk students for money. Glad I don't have to worry about all of that anymore. That being said, I did find Chemistry interesting and there are some things I'd like to study more in MY FREE TIME. But charging me thousands to sit through a class where I can't pick and choose what subjects I want to dive into is not interesting to me.
@@daytonasixty-eight1354 Yes I think that certain matter that I learn in school is absolutely pointless and in no way am I going to need this information in life, but I don't complain. The only reason why I don't complain is because despite the fact that this information is useless, learning it makes certain characteristics of our brain stronger such as problem solving. The only thing that needs to be fixed with school is that the field expects you to memorize the content, take a test, and then forget about it.
@@danielborisov5589 I don't think it helps with problem solving at all. Most of our problem solving abilities come from common sense. Much of it genetic. If you are a midwit, you will always be a midwit.
Dear Dr. Dave. Thank you for your great lessons. I've learned a lot from your series. This part is very hard and I need to watch this video many times to realize what happened to orbitals when their bond into a molecular form.
You really work very hard and that's why I am your very big fan. Replying to all questions in all videos and after 2 or 3 hours. Hats off to you sir!!!!
So ive been watching all your chem videos today because i have an exam tomorrow.And keep singing your intro music to everyone.i think its gonna be my ringtune now.

Hey Professor, thanks for all the vids! You just helped me save many hours annotating my textbook meticulously to make sure I have the important concepts down. Especially that one vid with Quantum Numbers. Entire weeks of knowledge summed up in a few mins...
I am going broke paying for my college, where I get lectured to by awful teachers. After I get off work (I have a job to help pay for my college), I go home to try and decipher what the teacher talked about that day. When I can't figure it out, I watch an 8-minute video, like this, that explains very well what my teacher failed to teach me in an hour. congratulations sir, you are making everything I do POINTLESS.
I've been so scared of chemistry all semester long until I found this channel kinda by accident. Just wanted to know something about the molecular geometry of one molecule and BAM, basicly a video to every topic I have to understand for my exam. Thank you so much, Dave!
you are pretty great. although i got A's in two semesters of college gen chem and two semesters of organic chem, this was a concept i opted to simply recognize patterns for, and/or general info to answer multiple choice questions for... but never truly "got it" until now. so thanks! love your videos!
Great video professor Dave. I just wanted to mention that not every energy level has s,p and d orbitals. Level one has one 1 s. Level two has one s and 3 p it is starting on the level 3 that d orbitals are present. I took chemistry a long time ago. Please correct me if I am wrong. Thanks for putting in the work to get these great video together.
nope you're absolutely right! i just spoke very generally to give people the foundation, and then when we run through the different energy levels they can see the specific orbitals present for each.
woah, thank you sir! this is the first time i really got this, my prof previously was talking too fast that i wasn't able to catch his trail of thought, now i understand it completely thanks!
wow,what a simple and easy explanation . I JUST LOVE TO WATCH YOUR CHEMISTRY EXPLANATION VIDEO " MR.DAVE". DO MORE AND MORE VIDEOS TO HELP THE STUDENTS TO MAKE THEIR CONCEPTS EASIER AND FOR THEIR BETTER UNDERSTANDING. "ONCE AGAIN THANK YOU"
Sir at 0:35 both 1s orbitals have spin up electron. Electrons with same spin can't reside at same energy so does that mean that one of the 1s electron change its spin in order to form a bond??
eh, i made an error referring to hybrid atomic orbitals as molecular orbitals, tried to fix it with annotations but it's egregious enough to merit a dislike.
Professor Dave Explains At least you tried fixing it , and even If you didn't , It was clear that you meant to say hybrid atomic orbitals , but haters will always hate I guess
ooh good question, you know i'm not sure that it does. but within a subshell the spins align, so it's possible that local electronic influences can dictate the spin. but when an electron is excited to a previously vacant subshell, i'm not sure what happens.
I don't know whether i should say this or not bt he just resembles ranbir kapoor alot the bollywood actor..!! well..i am from India n i appreciate your work thanks for your patience it really helped me :)
@ 6:00: "....so we need six 2p molecular orbitals" ~ shows and lists four 2p molecular orbitals. But overall this is a very clear instruction on how to go through the procedure. Thanks
Back when I was in high school, I saw lot of people complaining about their prof. remember thinking how bad could a prof's lesson be....Now that I am in college, I finally understand what they're like.
Nitrogen is going to have sigma - pi crossover, because of the unpaired electrons in the 2p subshell. So the sigma 2p is going to be higher in energy than pi 2p. Thanks for the effort you put in the making of you videos, keep up the good work :)

@ 6:00: "....so we need six 2p molecular orbitals" ~ shows and lists four 2p molecular orbitals. But overall this is a very clear instruction on how to go through the procedure. Thanks
Back when I was in high school, I saw lot of people complaining about their prof. remember thinking how bad could a prof's lesson be....Now that I am in college, I finally understand what they're like.
Nitrogen is going to have sigma - pi crossover, because of the unpaired electrons in the 2p subshell.
So the sigma 2p is going to be higher in energy than pi 2p.
