How does vegetable oil change by hydrogenation?
Answer and explanation
Correct answer: From an unsaturated liquid to a more saturated solid fat
Hydrogenation is an addition reaction in which hydrogen is added across carbon–carbon double bonds of an unsaturated oil, usually with a suitable catalyst such as nickel. This decreases unsaturation and raises the melting point, so the liquid oil becomes a more saturated, semisolid or solid fat. Option A is correct; the other options describe unrelated changes involving acids, salts, gases, or metals.
