... As they are unsaturated alkenes are reactive. The second bond of the double bond is weaker than a single carbon-carbon bond and is broken much easier. It is because of this greater reactivity that alkenes, especially ethene, are important starting materials in organic synthesis of useful chemicals. ...

In 1794, Joseph Proust (1754-1826) demonstrated the law of definite proportions (aka law of constant composition): In a given chemical compound, the proportions by mass of the elements that compose it are fixed, independent of the origin of the compound or its mode of preparation. In 1808, John Dalt ...
