Order of Stability of Radicals

Question 1

Give the order of stabiltiy of radicals.

Answer 1

CH3 < 1 primary < 2 secobdary < 3 tertiary.

Thus, reaction goes via most stable radical.

Question 2

Is primary or tertiary most stable radical for a reaction to occur via?

Answer 2

Tertiary radical = most stable = reaction more likely to occur.

Question 3

Is CH₃ or primary most stable radical for a reaction to occur via?

Answer 3

Using primary radical = more stable radical = reaction more likely to occur.

Question 4

What is initiation in free radical halogenation reaction?

What step is it?

Answer 4

Creation of free radical.

First step in free radical halogenation reaction.
