💡 Distillation fractionnée sépare les pétroles bruts en différentes fractions utiles.
💡 Le pétrole brut est un mélange d'hydrocarbures de différentes longueurs de chaînes.
💡 Les différentes fractions des hydrocarbures doivent être divisées par distillation fractionnée pour être utiles.
The strength of intermolecular forces increases with the size of the molecules.
Smaller molecules have weaker intermolecular forces and lower boiling points.
Larger molecules have stronger intermolecular forces and higher boiling points.
🧪 Fractional distillation separates molecules based on their boiling points.
⬆️ Long chains of molecules with high boiling points condense at the base of the column.
⬇️ Smaller molecules with lower boiling points condense higher up the column.
🛢️ Crude oil is an important mixture of hydrocarbons.
⚗️ Fractional distillation is used to separate crude oil into useful fractions.
🔥 Shorter hydrocarbon chains have lower boiling points and are collected at the top of the column, while longer chains have higher boiling points and are collected at the bottom.
