Показать описание
This chemistry video tutorial provides a basic introduction into VSEPR theory and molecular structure. It contains examples and practice problems of drawing lewis structures along with the correct molecular geometry. Structures include the tetrahedral shape, bent, linear, trigonal planar, and trigonal pyramidal molecular geometry as well as their bond angles.

The fact that I'm giving my tuition to my professor instead of you is really annoying. I owe you.

Who else is binging his videos because you have a test in 4 hours and haven't studied a thing

I write my final chemistry exam on Monday. So nervous but I’m so excited to finally be done with this stuff. Bit sad that I’m never gonna have to watch one of your videos again tho :( thanks for doing a better job than my teachers 😀

I'm in near tears. I was so lost with chemical bonding chapter but the formal charge thing really helped me up understand how people just somehow knew how to write certain molecules. I took that knowledge with this and now i finally can practice without anxiety. thank you so much, sir.

I just want to mention that the bond angle for trigonal pyramidal molecules, starting from NH3, is 107*. As you go down and to the left on the periodic table, elements get larger, meaning PH3 is larger than NH3 and AsH3 is larger than both PH3 and NH3; AsH3>PH3>NH3. Because these are larger molecules, their shells are further apart, making the bonds longer and weaker. This subsequently reduces the bond angles as the molecule gets larger. Unfortunately, just gotta memorize the numbers, but realize that it is NOT 107*.
NH3 = 107*
PH3 = 93.5*
AsH3 = 91.8*

I always watch the entirety of the ads in Julio's videos so that I can pay him back in some small way, however insignificant.

His voice is very soothing. I binge-watch without getting a headache. Thank you for your videos.

I've watched a bunch of your videos and they've been a life-saver. My professor is the worst but these explanations actually help. Thank you so much!

I appreciate you, JG. I've been watching your Chem and math videos since like 2016 and it really has helped me get a better understanding of the material. You are brilliant and really know your stuff. Thank you from the bottom of my heart for dedicating your time to teach us, AND always providing us with high quality material, for free. I wish you + your loved ones good health, happiness, success in whatever you put your mind to, and more life. May angel's protect you, trouble neglect you, and heaven accept you.

I’m having a hard time in Chem, something which is strange for me because I’ve never struggled with any classes before and my teacher isn’t helpful at all. Thanks to this tutorials I’ve been passing my tests

I have a test on a unit which includes this topic on friday but have not been taught it yet. This video helped me so much! Thank you!

going from 6 years of working to Biomedical science course, you will be the one thing giving me a fighting chance hahahha thank yu so muhc. you've literally helped me with physics, math and chemistry so far. you're a godsend i swear haha

Thank you for this channel! I appreciate that you've thoroughly structured your lessons, and you fill in all the gaps that my professor can't.

I love your videos man! Your voice is so soothing, too. My professor is great but he doesn't like to lecture (he wants to empower us to find our own solutions You have really helped to fill some holes in my comprehension.

Ever since you helped me get a A in physical chem. I used to listen to him videos in year phones to the last minute in the exam room. I would even visually what he would say if he was there looking at the exam
