1.	Give a test to differentiate b/w butter and vegetable oil?
Answer» Hydrocarbons are colorless. Bromine dissolved in water or trichloroethane solvent forms an orange (yellow/brown) solution. When bromine solution is added to both butter or cooking oil the result is quite different. The butter solution remains orange.As cooking oil is unsaturated compound so it decolorises the bromine as it forms a colourless dibromo- addition product.\xa0Cooking oil + Br2 → Addition product Butter + Br2 → No reactionButter contains saturated fats. Therefore, it cannot be hydrogenated. On the other hand, oil has unsaturated fats. That is why it can be hydrogenated to saturated fats (solids). Hydrogenation
