@@electro_yellow9295 Personally my professor sucks so I have to look up all the topics he tries to explain in class and teach myself. We don't even have a textbook, he teaches through handouts.

You have seriously saved my extremely frustrating experience with Chem!!!! My teacher blows but your videos have been so helpful. THANK YOU SO MUCH :))))))

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 wouldn't really call that smart, I know some people who revise constantly and still don't do well. I revise hours before exam and manage to do well somehow
@@MyTopAnime it's confidence that boosts your exam. i've found myself revising nothing and just messing around in the test and somehow getting it right many times. I'm not even that smart
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 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 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’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
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
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 eeeeeeeeekk). You have really helped to fill some holes in my comprehension.

@@abcdefg-hv2ks you’re right, i’m pretty lucky 😅 and thanks! it went well! i’m going to miss him next semester though :( i wish he taught more chem courses

With the Triiodide you showed at 2:00, how come the all the iodides have 3 lone pairs? The middle iodide has two bonds. Is that because it is in the fifth group and can in turn have more than 8 valence electrons?
Hey at 9:35 when you are drawing the SO2 molecule in lewis form, you draw it as having 1 double bond and 1 single bond between the oxygen. However, when I search the structure on google as well as in molecule structure situations it is always with 2 double bonds. I imagine this means that Sulfur has an overfilled octet because that is possible for sulfur. Can you explain why you draw it like that, is there a reason why it all 3 atoms should follow the octet rule(in your drawing), or should Sulfur be overfilled?
@theorganicchemistrytutor Would you mind increasing the volume of your recordings please? Its really soft and I've maxed out my Chromebook speakers Also, its a bit muffled . Thank you for your free videos 'cos I'm not a rich Chem student who can buy tutors
Why isn't I3 bent? Edit: it's not bent because it's EGG is trigonal bipyramidal, and so the lone pairs will be as far apart as possible and the farthest angles are the 120° ones and so all the lone pairs will be on the "planer" part of the shape, leaving only the axial bonding pairs 90° from each lone pair so the molecular geometry is linear. Idk why he mentioned it with the other one who's egg was linear and not with the other trigonal bipyramidal
