Omg I needed this. Also i actually went to your website and got the sample test and answers, and that was so worth it!! The information is going on flash cards ASAP.
I feel like you practically added a few more years to my life with these videos man. You make this stuff so easy to understand. I can't thank you enough.
Hi Mr DeWitt! You have helped me perform very well in Chemistry this year, and I just wanted to tell you how much I appreciate your help for every single topic! :) I'm really glad to see you now as I've been watching your videos that were released 7-10 years ago. I truly appreciate it! :D
Ohh my god 😭😭😭😭... I'm so happy seeing your video after long time .... Please do as more topics as you can ... You are the only one who can make me understand complex topics in chemistry ❤️❤️...i am very very much thankful to you ❤️❤️❤️... I love you sir you are the best ❤️❤️❤️❤️❤️
I love your positivity and I agree, this TH-camr is quite helpful!! Also please don’t use the Lord’s name in vain, just a suggestion :). Have a blessed day!! and good luck in your classes!!
8:52 shouldnt it only be H bonding because mentioning hydrogen bonding implies that dipole-dipole interactions are present, as hydrogen bonding is a subset of dipole-dipole interactions
Thank you so much for your help! I'm really nervous about my upcoming test on Monday, but your recent videos have given me so many last-minute tips. I feel so much more confident now!
You are such a great teacher I found on the last minute of my test and passed in electrochemistry I'm really really glad to find you your teaching amazes me like I used to hate chemistry and after finding you I was just like that how a subject can be sooo fun will you please explain organic chemistry from basic it's my humble request please????
Hi ty, i learnt the chemistry from scratch by seeing your videos now after i read my class 11 book, the feel of understanding is just awesome man.... thanks a lot..
AP Chem? I'm in basic Chemistry 1 and have to know all this, which sucks since I'm just trying to go for a mechanical engineering degree. But do really appreciate all your videos!
Yes and no. The actual angle depends on the identity of the atoms. Sometimes it’s 104.5, sometimes less, sometimes more. It’s not *always* 104.5 in this case. However, the ideal theoretical is 109.5, which is why it’s acceptable to say 109.5, or “slightly less than 109.5.”
Could you make a video on Lewis Dot structure? you explain stuff the best out of any TH-cam channel video or teacher I've every had or anyone friends whoever that has taught me chem ever. Thank you.
Thank you so much! You have saved me twice already just in the past two weeks. However, just one question - for 5:07, why is it not Bent, like H2O? The O in H2O also has 2 single bonds + 2 lone pairs, but H2O would be bent and
Well the bond in H2O is about 105°. Yes it is a bent geometry, but it is based on a tetrahedral geometry, which has a 109.5° bond angle. So yeah, if those electron pairs didn’t repel so much, it would be 109.5°, and 105° is close enough that the difference doesn’t matter for the test.
In water molecule H2O.. oxygen has two bond pairs and two line pairs… just like C-H-O… so shouldn’t it be a V shape and the bond angle should be 104.5?
Right, and that’s why I said “the bond angle is a little less that 109.5°, but for the AP Exam you just need to know the approximate value, and 109.5° is fine.”
@@birdie7344 i finished it half an hour ago. I think it went well considering i did not study much. Most importantly, there were many similar questions to the ones in these videos.
Thank God there's a non AP way of gaining college chemistry credits. Alot of these free response questions are intentionally creating a hatred of chemistry rather than fostering a love of it.
@@tdewitt451 Specifically I would have to get back to you but GENERALLY, the types which are as involved as the one discussed. A general video helping to explain and giving tips which will aid in deciphering when parts of the problem are dependent on prior parts versus independent, would go a long way to helping cure that problem.
@@tdewitt451 you are so welcome. Last semester I took chemistry 121, I was so lost and In dispare. I got a tutor, and also watched your videos. Between the 2, I got a B in the class. Do you have microbiology videos, as well? I’m taking micro 250 this semester. Final is in a week, but I wouldn’t mind turning my B, into an A.
For the IMFs question, is it necessary to mention how both methanol and formaldehyde also have LDF attractions with the polarizability of their electron clouds? I heard that you should always mention all types of IMFs on the AP exam
Because I hardly make any money from these videos. Every time I make a video I lose money because my real job pays much better. Would you like to pay me to make the videos, so I don’t lose money? If so, I would be happy to make videos for IIT. The truth is, I am trying to find a way to do it, but I don’t know how I can make enough money.
No one will replace Mr.Dewitt teaching... Such a Nice explanation in detail
FACT.
It is currently dark outside and I was stressing about my test tomorrow! You, sir, are freaking amazing! Thank you so much for the help!

I’m so glad you’re back doing videos! You’re a chemistry treasure 💎
Probably the best chemistry online tutor"
You are back!!! I remember watching your videos on what moles are in grade six and now watching this for A2 Chemistry!
I hope it’s helpful!
omg. im done all my chemistry uni courses now but im so glad this guy is back on youtube!!! definitely the reason i survived university

Thank you very much professor!
I've been watching your videos since 2015...
Sir, my daughter so GRATEFUL for your such amazing teaching!! THANK YOU THANK YOU THANK YOU! 🙏🌷🌷🌷
Just took the AP test, and your videos were great help! Thank you!
Thank you so much for returning on yt. We all love the way you teach. Thanks a ton to you, I am interested in chemistry😂❤
I love these glad to see you are uploading new videos. I just started taking chemistry again and your videos always help. Thank you for everything :)

Me too we got this
Man AP Chemistry is easy with your videos, I started 5 days ago now I already finished unit 2 on the book, woohoo!!!
You are seriously out here doing God's work. Thank you so much for these videos
You're such a vibe. Glad you're back. Watching your videos has been a plus to me
Crystal clear explanation
Thanks from INDIA 🇮🇳

You are the people's hero. I aspire to teach like you one day.
Thanks bro… you saved my life
How good this channel is, i'm the chemistry student at university
Im so happy your back man 😭😭😭😭😭😭😭😭😭your videos are the best
YOURE THE BEST!! If u could create one on mcq that would be so great !!
I have one on 20 multiple choice questions! Check out my website at tdwscience.com/apchem
Ureka!! Mr Tyler is back!!
You have helped me out so much thank you for all you do!
I already graduated I just love watching these videos
He's the goat of physics
You're back! I missed you!
Hey man, thanks for existing
AP Chem? I'm in basic Chemistry 1 and have to know all this, which sucks since I'm just trying to go for a mechanical engineering degree. But do really appreciate all your videos!
great confidence booster :)
Omg, I just discovered you returned to TH-cam!
Just love to see you teach🙏
I hate chemistry thanks to my teacher, only reason I subbed this guy is the most amiable way in which he explains.
Best teacher out there oh my goodness
OMG HE IS BACK THANKYOU
Thank you for helping me throughout my exams!
You're a nice teacher than my teachers. Lols, they didn't explain the whole thing they just gave an assignment to us.
Sir you really made chemistry easy
3:44 shouldn't it be bent(104.5) since it has 2 lone pairs and 2 bonds?

Taking mine in an hour. TYSM for your help
Good luck!!!
@@tdewitt451 Update: I got a 5! Thanks for your help btw
You are the best 👌
😍I feel the chemistry between us
OMG HE IS BACK. PLS NEVER LEAVE US AGAIN 😭😭
YESSS:( he teaches SOO WELL
Thanks a lot sir... Keep posting more videos...
I hope, you will make more videos for us. Thanks so much.
Could you make a video on Lewis Dot structure? you explain stuff the best out of any TH-cam channel video or teacher I've every had or anyone friends whoever that has taught me chem ever. Thank you.

I take mine today.. thank you
can we use uranium U238 or Thorium as anode electrode in a battery ? to make battery 🔋 with 22,394,000,000 Wh/kg energy density?
You're our hero ⭐
Thank you sir so much. Can you do about enthalpy too
Can you make a video on molecular orbital theory and postulates Mr Dewitt?
Thank god for Tyler
Bro thx I passed the exam and get my teacher's daughter no. (She's soo stunning)
thank you for this series
OMG YOU ARE BACK
The lone pairs in formaldehyde is not counted???
Thanks for these videos!
Thanks Tyler, very nice.
Ur unique sir 🙏

Sir, could you make a lecture on "Le Chatelier's Principle". Plz
You are so awesome!
thank you hahah
yes i know
@@WRDO I was speaking of Tyler :)
I appreciate it! Many thanks!

Do you have microbiology videos, as well? I’m taking micro 250 this semester. Final is in a week, but I wouldn’t mind turning my B, into an A.
Please need an explanation on Bohr's model as it becomes very hard to understand quantized energy and angular momentum. Thanks in advance.
For the IMFs question, is it necessary to mention how both methanol and formaldehyde also have LDF attractions with the polarizability of their electron clouds? I heard that you should always mention all types of IMFs on the AP exam
You don’t need to there, because the LDF’s really aren’t relevant for explaining the *difference* in boiling points. But great question.
Please can you make videos on titration and back titration
Thank you sir...
Please make a video on HYBRIDISATION...
Good video
Very nice👍
please do a video on solubility rules!!
and ksp and all that good stuff, just a suggestion. !!
Hey can anyone recommend any AL physics teaching videos available in youtube
We have polar and dipolar concepts video
. Pls put on the video
Where was this when I had Ochem finals last week?
Please continue your channel on mot
Make a video on how to find no of isomers ?
sir please make a video about gibb's free energy and ionic equilibrium......that would be very helpful
Isn't the formula for Delta H = Delta H of Reactants - Delta H of products?
No.
That’s for bond enthalpies
The Man The Myth The Legend
Tylerr Dewitt
About 3 months to late for me but still, thanks for making these.
my chemistry dzaddy 🥵 is back from a long time 🥵🥵
Sir why can't you make videos for the IIT Jee chem exam? Many of your Indian students requested you the same but you didn't response.
Because I hardly make any money from these videos. Every time I make a video I lose money because my real job pays much better. Would you like to pay me to make the videos, so I don’t lose money? If so, I would be happy to make videos for IIT. The truth is, I am trying to find a way to do it, but I don’t know how I can make enough money.
@@tdewitt451 Well said sir. Everyone needs money so do you. Thanks for acknowledging the question.
gracias por existir
