Concept explainers
(a)
Interpretation:
The product formed when cholesterol reacts with hydrogen in presence of palladium-carbon has to be drawn.
(a)
Explanation of Solution
Cholesterol with hydrogen:
Cholesterol reacts with hydrogen in presence of palladium-carbon to reduce double bond to single bond and forms cholestanol. Therefore, the product obtained is cholestanol which is shown in the above scheme.
(b)
Interpretation:
The product formed when cholesterol reacts with acetyl chloride has to be drawn
(b)
Explanation of Solution
Cholesterol with acetyl chloride:
Cholesterol reacts with acetyl chloride in which acetylation reaction take place at hydroxyl group and forms cholesteryl acetate. Therefore, the product obtained is cholesteryl acetate which is shown in the above scheme.
(c)
Interpretation:
The product formed when cholesterol reacts with sulfuric acid followed by heating has to be drawn.
(c)
Explanation of Solution
Cholesterol with sulfuric acid:
Cholesterol reacts with sulfuric acid in which removal of water molecule take place and forms cholestene. Therefore, the product obtained is cholestene which is shown in the above scheme.
(d)
Interpretation:
The product formed when cholesterol reacts with water in presence of acid has to be drawn.
(d)
Explanation of Solution
Cholesterol with water:
Cholesterol reacts with water in presence of water in which removal of water molecule take place and forms desired product. Therefore, the product obtained is is shown in the above scheme.
(e)
Interpretation:
The product formed when cholesterol reacts with peroxy acid has to be drawn
(e)
Explanation of Solution
Cholesterol with peroxy acid:
Cholesterol reacts with peroxy acid in presence of water in which reaction take place at double bond and forms
