Answer
The process is called hydrogenation because the resulting fats are saturated with hydrogen bonds (i.e., the number of hydrogen bonds increases).
Work Step by Step
Hydrocarbon chains in vegetable oils have to be saturated to be converted into a semisolid compound. The process is called hydrogenation as the conversion of carbon-carbon double bonds in unsaturated fats to carbon-carbon single bonds requires the addition of hydrogen atoms.
