For each compound, predict the major product of free-radical bromination. Remember that bromination is highly selective, and only the most stable radical will be formed.
The stability of radical increases as the number of alkyl groups bonded to the radical carbon increases.
The allylic radical is more stable than the other radicals because two resonance structures can be drawn.
Allylic radical is more stable than tertiary radical, and a secondary radical is more stable than a primary radical.
Treatment of cyclohexene with bromine in the presence of light gives bromocyclohexane. Thus, the reaction is as follows:
Treatment of methylcyclopentane with bromine in the presence of light gives 1-bromo-1-methylcyclopentane. Thus, the reaction is as follows:
Treatment of decalin with bromine in the presence of light gives 4a-bromo decahydronaphthalene. Thus, the reaction...
