Reactions of Alkanes

 Reactions of Alkanes

1. Halogenation of Alkanes

Halogenation is a substitution reaction where hydrogen atoms in alkanes are replaced by halogens (Cl, Br). The reaction occurs via a free-radical mechanism involving initiation, propagation, and termination steps.

Preparation of Alkanes

Preparation of Alkanes:

1. Hydrogenation

Hydrogenation involves the addition of hydrogen to unsaturated hydrocarbons (alkenes or alkynes) in the presence of a metal catalyst such as Ni, Pd, or Pt, under elevated temperature (250°C).
