Please explain why the reaction of neopentane yields 1- chloro- 2,2-dimethyl propane when treated with chlorine molecule during free radical mechanism ?
why not 1,2 methyl shift to give more stable tertiary free radical as compared to less stable primary free radicle????
please reply.

because for 1,2 me shift carbocation is necessary
free radical cannt be shifted mind it

in this type of reaction free carbocation is not formed
and for any shift carbocation is necessary , so no shift occurs
u can refer sn sanyal for reactions and mechanisms
