C6H5Br does not undergo SN2... it undergoes substitution by benzyne mechanism.
So C(Me)3Br>>>>>>>>>>>>>>C6H5Br for SN2!!

c(me)3br forms a 3 degree cation na. so why will it take part in sn2 leaving sn1?

no it is not the meaning the 3 degree cation can undergo SN2 rxn but veryveryveryveryveryveryveryveryveryveryvery less da

but if u compare this qn the ans would be like c(me)3-br>phbr.

becos in SN2 rxn back side attack is one of the step.this is impossible in phbr
