Section D: Conceptual Questions
  1. Why is the conversion of ethanol to ethanoic acid considered an oxidation reaction?
  2. Why do unsaturated hydrocarbons burn with a yellow flame with lots of black smoke?
  3. Carbon cannot form ionic bonds. Give two reasons why.
  4. What are oxidizing agents? Name two oxidizing agents used in organic chemistry.
  5. What is the role of concentrated Sulphuric acid in the dehydration of ethanol?
  6. Explain the cleansing action of soap with the help of a diagram. (Draw Micelle).
  7. Why does micelle formation take place when soap is added to water? Will a micelle be formed in other solvents such as ethanol?
  8. Why are detergents better than soaps for laundry in hard water?
  9. Differentiate between soaps and detergents on the basis of their chemical composition.
  10. Why does carbon form a large number of compounds? (Two properties).
