Other questions in this quiz

2. What is a functional group?

  • A group of atoms or an atom which give a compound distinctive properties
  • The -COOH in an alcohol , for example
  • A family of molecules that all have a homologous series attatched
  • The columns of the periodic table

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

  • A ketone can be formed from the oxidation by distillation of a primary alchol
  • 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
  • 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
  • An ketone will form a dark red precipitate of Copper(I) Oxide with Fehling's solution but an aldehyde will not

4. What is the product of a halogenalkane reacting with KOH under ethanolic conditions?

  • An alcohol with a halogen group (addition)
  • A salt and water
  • An alkene, water and KX (elimination)
  • An alcohol and KX (subsitution)

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

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