WebBromine forms a free radical in the presence of sunlight, then bromine abstracts a hydrogen to form most of the stable radical. Bromination occurs selectively at the highest substituted carbon of alkane. Intermediate free radical is most stable due to a tertiary carbon. So it will be the major product.
