Question

Cooking oil can be converted into vegetable ghee by the process of:

• A. hydrogenation
• B. distillation
• C. crystallisation
• D. oxidation
• E. ionisation

Answer 1

The correct option is A hydrogenation

Hydrogenation is a reduction reaction which results in an addition of hydrogen (usually as $H_2$). If an organic compound is hydrogenated, it becomes more 'saturated'. Hydrogenation has many applications, but most people are familiar with the reaction as the one used to make liquid oils into semi-solid and solid fats
