Solution

In the free radical bromination of sec-butylcyclohexane, bromine selectively attacks the most stable radical intermediate, which is the tertiary ($$3^\circ$$) carbon at the ring junction (Carbon I). This specific position is prioritized over the side-chain tertiary carbon because it is stabilized by a higher number of $$\alpha$$-hydrogen atoms through hyperconjugation.
