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.

Well explained and organised

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

@Leah4sci

2 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
