Karl Ziegler reported that alkenes react with N-bromosuccinimide (NBS) in presence of light to give products resulting from substitution of hydrogen by bromine at the allylic position i.e., the position next to the double bond. Let us consider the halogenation of cyclohexane. Energy level diagram for allylic vinylic and alkylic free redicals is given below: Consider the three types of C-H bonds in cyclohexene. Which of the following `is // are `correctly matched?
