The first step of the sequence utilizes hydrogenation (Pt) to convert 3-methyl-1-pentene into 3-methylpentane. The second step uses bromination (Br2 or NBS in the presence of light or heat) to brominate the tertiary carbon at the 3-position. It is important to note that NBS (N-bromosuccinimide) is a more selective reagent and is preferred over using Br2 directly.
