来源说明
This Br2/UV bromoalkane branch uses ethane mono-bromination as the mechanism exemplar. Longer or branched alkanes can still give positional isomer mixtures and termination by-products; this route does not generalize a full downstream bromoalkane route family.

    Supports alkane reaction with Cl2 under ultraviolet light to form chloroalkanes by radical halogenation, including initiation, propagation, termination, product mixtures and multiple chlorination; analogous bromination is retained as a scope boundary.
