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 Жыл бұрын
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.

Is the part where the CH3 radical joins with the Cl radical to form a halogenoalkane a part of propagation or termination?
@Leah4sci4 ай бұрын
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

@MeetYukiSimba8 ай бұрын
you know at 7:15, why does the radical choose to bond with hydrogen and not methane??
@Leah4sci8 ай бұрын
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.

Propagation doesn't increase the number of radicals in solution.
