Raghav is a student of class X who was trying to convert the groundnut oil into solid fat (vanaspati ghee). He took the oil inan appropriate flask having an arrangement for passing hydrogen gas into it. Raghav pased the hydrogen gas into oil and heated them together for a considerable time. On cooling the apparatus, Raghav found that even after heating them together for a considerable time. On cooling the apparatus, Raghav found that even after heating together oil and hydrogen for a considerable time, no solid fat was formed. Raghav shard this problem with his sister Divya who is studyging in class XI. She advised him ot add a certain finely divided substance while heating oil wih hydrogen gas. When Raghav repeated the experiment by adding this substance to oil and hydrogen mixture, then the liquid oil was converted into a solid fat.Divya advised Raghav not to consume the fat prepared by him in the laboratory. (a) What was he finely divided substance which Raghav was asked to add for converting oil into fat? What is its function? (b) What type of substance is (i) an oil, and (ii) a fat? (c) What is the special name of conversion of oils into fats used in Industry? (d) What are the two types of chemical reactions exemplified by the conversion of oils into fats?
