The reaction of propane with bromine in presence of UV light predominantly forms
Options:
Answer:
B
Solution:
The reaction of propane with bromine in the presence of UV light proceeds via a free radical substitution mechanism.
Bromination is highly selective and favors the formation of the more stable free radical intermediate.
Propane () has primary and secondary hydrogen atoms. Abstraction of a secondary hydrogen yields a secondary free radical, which is more stable than the primary free radical formed by the abstraction of a primary hydrogen.
Thus, the major product is 2-bromopropane.
Answer: 2-Bromopropane
