Free radicals reactivity in increasing order is :

3degree  <  2degree  < 1 degree

stabililty reverses the order,

this is due to the fact that 3degree carbon atom has the maximum possible hyperconjugated structures thus INCREASING its stability and DECREASING its reactivity.

hope this helps!!

1 degree>2 degree>3 degree

 

as 1 degree free radical is less stable tan the rest, it will tend to react tan the others.... and as 3 degree is more stable tan the others, it reacts less compared to others...

free radical stability or order of reactivity is just like carbocation...i.e. 3degree > 2degree > 1degree...

To get rid of your confusion for stability of free readicals,

Always treat free radicals as carbocation ( only for comparing) and then solve the problem.

stability of free radical depends upon electron donating group which is present.

More the number of electron donating group attached to free radical more is the stability.

Best of luck1

May god bless you!

3 degree<2 degree<1 degree

because alkyl group is electron donating group it pushes its electrons towards the central atom

so stability increases and reactivity decreases

The stability order is 1 degree > 2 degree > 3 degree based on the no of hyperconjugative structures

Every mithyl group has a non hybridized electron which  is shared to the central carbon and that’s why the stability of free radical increases. so those who has more mithyle group has more stability.
