Study Notes
Hydrocarbon Reactions
-
Hydrogenation: Unsaturated hydrocarbons (alkenes/alkynes) react with dihydrogen gas (H2) in the presence of catalysts (like Pt/Pd/Ni) to form alkanes.
-
Alkyl Halides Reduction: Alkyl halides (except fluorides) react with dilute hydrochloric acid (HCl) in the presence of zinc (Zn) to form alkanes.
- The reaction is represented as R-X + Zn + dilute HCl → R-H.
-
Alkyl Halides and Sodium in Dry Ether: Alkyl halides (excluding fluorides) react with sodium (Na) in dry ether to produce higher alkanes. This will depend on how many carbon chains are in the alkyl halides being used.
-
Alkyl Halides and Zinc Chloride: The reaction of alkyl halides with zinc chloride (ZnCl2) and dilute HCl leads to the formation of alkanes.
