Which of the will give 2,2- dibromopropane on reaction with HBr?
Which are free radical reactions
I.CH3−CH=CH2+HBrPeroxide−−−−−→CH3−CH2−CH2BrII.CH3−CH=CH2+HBr→CH3−CHBr−CH3III.CH3−CH=CH2+Cl2→ClCH2−CH=CH2IV.CH3−CH3+Cl2→ClCH2−CH3
An alkybromide(A) On treatment with Na and ether gives a hydrocarbon (B). (B) on treatment with HBr and Peroxide gives Br - (CH2)6−Br compound (A) is
