Explanation:Cracking is an important petroleum process that breaks heavy hydrocarbons into lighter, more useful fractions.
Polymerization is also used in the petroleum industry to join small unsaturated molecules into larger hydrocarbons.
Saponification is the alkaline breakdown of oils and fats, so it is linked to soap production and can also be used to analyze petroleum products.
