Unsaturated Hydrocarbon Reactions (HSC SSCE Chemistry): Flashcards

Alkenes (C=C double bonds) and alkynes (C≡C triple bonds)

Double/triple bonds weaker & easier to break than single bonds

$\text{CO}_2$ and $\text{H}_2\text{O}$ only

Atoms added by breaking multiple bond; all atoms in product

Adding $\text{H}_2$ to unsaturated hydrocarbon

Metal catalysts: Ni, Pt, Pd, or Rh

No - halogens highly reactive

Unsaturated compounds decolourise bromine water

Alcohols

H adds to carbon with more H atoms already attached
