Peroxide Effect

In the presence of organic peroxides, the addition of $H B r$ to an alkene follows an Anti-Markovnikov pathway.
Mechanism: This is a free radical mechanism. The peroxide generates $B r^{.}$ radicals. The bromine radical adds to the less substituted carbon to form a more stable substituted carbon radical intermediate.
Example: Propene $+ H B r + peroxide \to$ 1-Bromopropane.
