10.1 Free Radical Halogenation | Organic Chemistry
Chad summarizes the three free radical halogenation reactions: chlorination, bromination, and allylic or benzylic bromination with NBS. He explains the selectivity associated with bromination reactions and how to calculate the relative amounts of products formed in free radical chlorination and bromination reactions. He then covers allylic bromination and benzylic bromination using N-bromosuccinimide (NBS). Finally, Chad concludes the lessons by providing an example of how to determine the number of monochlorination products for a reactant.

unlucky to study these topics in 12th standard...INDIA But thankyou I was confused where to substitute chlorine on 0,1,2or 3 degree to find major product
So if Br prefers the most substituted carbons, how can we make primary alkyl bromides, like 1-bromobutane, for example? :q Could radical bromination do that somehow? Or do we need to put an -OH group at the end of the carbon chain first and then substitute it with bromine? But if the latter is the case, we still need some way to put the -OH group at the end of the chain (let's suppose we don't have the alcohol yet, just an alkane). Wouldn't it involve putting another leaving group there (i.e. the halogen) in the first place? How is the usual way of doing it?
thank you
