Other questions in this quiz

2. What is the catalyst for the hydration of ethene into ethanol?

  • Potassium (VIII) manganate
  • Nickel
  • Phosphoric acid
  • Iron

3. Why is 2-Bromopropane the major product of the reaction of propene and HBr?

  • The H will attack where there are fewer H's already
  • Because the intermediary carbocation is more stable (the charge is spread over more atoms)
  • There is less steric hinderance for the reaction compared to 1-Bromopropane
  • It is not, the products are equally likely as propene is symmetrical

4. Momomers are...

  • Alkanes that form polymers by addition reactions
  • The singular repeat units that form a polymer (after the double bond has been broken)
  • The alkenes that form a polymer
  • Alkenes with only one C=C double bond

5. What is the difference between a ketone and an aldehyde?

  • An ketone will form a dark red precipitate of Copper(I) Oxide with Fehling's solution but an aldehyde will not
  • A ketone has an C=O group in the middle of it's molcule, thus with an alkyl group on each side. In an aldehyde the C=O is found at the end of the molecule with an H and an alkyl group
  • A ketone can be formed from the oxidation by distillation of a primary alchol
  • An aldehyde has an C=O group in the middle of it's molcule, thus with an alkyl group on each side. In a ketone the C=O is found at the end of the molecule with an H and an alkyl group
