I am a student in china. This year I will take part in the college entrance exam.Chemistry had been the most difficult subject for me.But when I find your video by chance, I began to understand the secret to chemstry. You are the best chemistry teacher I have ever seen.Thanks for your devoting!
I'm from Ghana and I've been finding it very difficult to understand this based on how our Professor taught us but after watching this video everything is clear now YOU ARE THE BEST
A classmate of mine recommended this video and I'm so glad she did. I felt so stupid for not getting it when truly I just didn't get it explained to me in a simple enough manner. Thank you so much!
I'm glad your friend shared this with you. Too often professors and books teach at a very high and less than understandable method. So glad this resonated with you
I'm student in Russia. I've always had problems with chemistry, but not a single lecture in my native language could help me meaningful. And so, I'm so desperated that I start watching videos in English and to my surprise your videos could help me understand some of the topics. IDK should it be funny or not, but I'm grateful to you. Right now, I hope to be able to take the alkane test tomorrow :')
I'm happy to hear you're finding the videos useful. I know organic chemistry can be tough, but I'm happy to help fill those gaps and clear things up for you.
We just started this chapter today and was told to read over the notes but could not understand anything in the book, this broke everything down so we'll and neat thanks so much
I barely comment on videos but I had to comment on this one because it helped me to get through one of the topics that I have difficulties with in my organic chemistry course
WOW! i never comment but i hv to say that this lesson couldn't have been explained better or clearer than you did. Thank u so much i really appreciate this!
I was panicking because I have organic exam tomorrow and I don't understand anything they taught in lecture but I guess I got so lucky finding your channel and I end up understanding everything and now I feel calm because now I have you to teach me really love your teaching thank you ❤
Wow that's awesome! I'm so glad I could help you out last minute. Let me know how it goes and if you need help as you close in on your finals reach out to me at leah4sci.com/contact for more resources.
Hello Leah4Sci, your lecture is wonderful as you know I have learnt this course it is a little bit difficulty but I passed the exam and I am 😃. Please create more videos and keep it up. Thanks 🙏 for sharing with me, my friend. Good luck 👍
Thank you so much, I was so confused as to how we knew when to stop propgation but now it makes sense. Basically when we've formed 2 different radicals. Then we can go to terminantion and bring those 2 radicals together right?
You're welcome. In most cases, propagation never stops. It is the most common step of the radical mechanism. Termination very rarely occurs and only when two separate radical species interact. You should never expect complete termination of the reaction.
Propagation means to propagate or continue. When a radical attacks something to form or propagate another radical, that is propagation. But when 2 radicals come together they form a bond. This 'terminates' the radical making it a termination step
I wanted to say thank you so much but I do have a question about potential energy vs reaction coordinate of these radicals I wanted to ask why binding of cl2 with hydrogen radical makes P.E of products more than binding of H2 and clorine radical which is also exothermic . I appreciate it if you answered and thanks for this amazing lecture...
You're welcome. Unfortunately, I don't offer tutoring over social media. For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
The hydrogen that it attacks IS a part of methane (which is CH4). It is much easier for it to pull off the terminal hydrogen than to attack the carbon at the center of the molecule. First, the central carbon already has a full octet and isn't susceptible to attack. Second, the newly formed methane radical is more stable than a single hydrogen radical would be.
so just to clarify. Termination technically happens once in a blue moon? How would i be able to show that step if my professor asks. Since propagation can happen over and over
Correct! I still show what a termination step looks like with examples at 8:40 in the video. I'm sure your professor will ask you to be able to draw this or identify this at some point, so it's worth the review. :)
I'm not following your question. Feel free to reach out to me through my website at Leah4sci.com/contact and rephrase the question with video and time stamp included. Thanks!
Propagation doesn't increase the number of radicals in solution. If you look at one of my propagation steps, you'll see it has one radical on the reactant side and still one radical on the product side. It just changes the identity of what that radical is.

In the example provided in this video, there were three termination steps that produced three non-radical termination products.

wow this stuff was dark magic for me for the past 9 months and this 12 min video cleared it all the night before my exam. thank you so so much
Wow, so glad to hear it! I hope the exam went really well. :)
I hope I can clear my doubts every time before tests and exams, just like you. Really hope that my wish comes true!
This explains it so well! My professor spent 2 seconds on this and then said we had to know it for my test on Monday. Thank you!
Ouch! So glad I was able to help fill in the gaps!
🤣🤣🤣
Out of curiosity, how'd the test go?
@@PunmasterSTP I don’t remember what I got on that test, but I aced the class so I assume it went well😂
@@s.p.8508 Sounds good 👍
OMG! I can't believe this video is only 2 months old! I needed this right now!! Thank you so much
WOOHOO for perfect timing!
Out of curiosity, how'd the rest of your class go?
I have an organic exam on this next week. This is super helpful
Love that this came at the perfect time for you! When next week? (I hope to publish part 2 next Tue)
How'd it go?
that's gonna be me in a few days😂

Is the part where the CH3 radical joins with the Cl radical to form a halogenoalkane a part of propagation or termination?
Propagation means to propagate or continue. When a radical attacks something to form or propagate another radical, that is propagation. But when 2 radicals come together they form a bond. This 'terminates' the radical making it a termination step
such a nice video, just watching for fun because i lvoe chemsitry
Yay! I love it, too, and I'm thrilled to hear of someone else who thinks chemistry is fun.

you know at 7:15, why does the radical choose to bond with hydrogen and not methane??
The hydrogen that it attacks IS a part of methane (which is CH4). It is much easier for it to pull off the terminal hydrogen than to attack the carbon at the center of the molecule. First, the central carbon already has a full octet and isn't susceptible to attack. Second, the newly formed methane radical is more stable than a single hydrogen radical would be.

You're very welcome. monosubstitution of methane with chlorine is just one specific example of this reaction (in other words, yes)

Very nice explanation please make videos on all chapters we need you your fan from india

Quiz on this tomorrow!!
Hope this video has you prepared to ace it
H2O may have unpaired electron pair, yet it is so stable
H20 has 2 lone pairs of electrons, there are no unpair electrons on a water molecule

Can we say that we use 3 number of ch4 and cl2 molecule???
