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!
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 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
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
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!
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 👍
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
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.
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.
mam plz start organic for joint entrance exam ( jee main & advance india) this is really helpful mam & I m so lucky I found this channel before my jee 2022❤️
I'm glad you're finding my videos helpful. I currently don't have plans to make JEE Main videos but feel free to utilize what I have to prepare for your exam
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...

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
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. :)
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. 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.
How to answer this question in a test Explain in your own words, how the first propagation step occur without energy input if it is energetically unfavorable?

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😂

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
@Leah4sci thank you for clarification !!
thank u for this wonderful lecture mam, I understood this topic very well, thank u so much
Glad to hear it and you're so welcome!
such a nice video, just watching for fun because i lvoe chemsitry

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
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

your explanation is phenominal! thank you so much, god i hate this topic in a level chemistry haha
Happy to help! I hope I help you not hate it as much, maybe even start to like it???
Out of curiosity, how'd the rest of your class go?
Thank you so much man ❤️
You're very welcome!
wouldn't the propagation step create enough free radicals at one point for the termination to be a common step in the reaction?
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.

This video does cover the radical halogenation of an alkane. Is there a specific point in this video that you have a question?
Thanks a million!

youre a life saver thank you

ILY thank you for this video!!! may I know if this is same as “monosubstitution of methane with chlorine” ? cuz this is what my textbook writes
You're very welcome. monosubstitution of methane with chlorine is just one specific example of this reaction (in other words, yes)
@@Leah4sci thankyou!!!
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.
