12 questions. Pick an answer and you'll see why right away. Options are shuffled each attempt, and the review at the end links each missed question to the dot point to revise.

  1. The IUPAC name of CH3CH(OH)CH2CH3\text{CH}_3\text{CH(OH)CH}_2\text{CH}_3 is:

  2. Propan-2-ol is heated with acidified potassium dichromate. The organic product and the observation are:

  3. A student heats 2-methylpropan-2-ol with acidified potassium permanganate. What happens?

  4. Ethanoic acid and propan-1-ol are heated under reflux with a few drops of concentrated sulfuric acid. The organic product is:

  5. But-2-ene reacts with hydrogen bromide. The product is:

  6. Which pair of compounds are structural isomers of each other?

  7. Which compound can exist as cis and trans isomers?

  8. Butane, propanal and propan-1-ol have similar molar masses. Their boiling points, from lowest to highest, are:

  9. An infrared spectrum shows a very broad absorption from about 2500 to 3300 cm−1^{-1} and a strong, sharp absorption near 1710 cm−1^{-1}. The compound is most likely:

  10. 12.0 g of ethanol reacts with excess ethanoic acid and 15.0 g of ethyl ethanoate is collected. Given M(ethanol) = 46.07 g mol−1^{-1} and M(ethyl ethanoate) = 88.10 g mol−1^{-1}, the percentage yield is closest to:

  11. Ethanol can be made by fermentation, C6H12O6→2C2H5OH+2CO2\text{C}_6\text{H}_{12}\text{O}_6 \rightarrow 2\text{C}_2\text{H}_5\text{OH} + 2\text{CO}_2, or by hydration of ethene. Using M(glucose) = 180.16 and M(ethanol) = 46.07 g mol−1^{-1}, which statement is correct?

  12. Which statement correctly compares addition and condensation polymerisation?
