[@user-oj9le4dz4z]

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!

[@Leah4sci]

You are so very welcome! I'm glad my resources are helping you to understand and reach your goal!

[@s.p.8508]

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!

[@Leah4sci]

[@estherabass7389]

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?

[@Leah4sci]

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.

[@981unknown]

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...

[@JulianMartinez-di2rt]

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

[@Leah4sci]

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. :)

[@theboredpeeps5824]

Is the part where the CH3 radical joins with the Cl radical to form a halogenoalkane a part of propagation or termination?

[@Leah4sci]

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

[@bookishdaydreams4993]

[@MeetYukiSimba]

you know at 7:15, why does the radical choose to bond with hydrogen and not methane??

[@Leah4sci]

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.

[@shobarbaba]

wouldn't the propagation step create enough free radicals at one point for the termination to be a common step in the reaction?

[@Leah4sci]

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.
