Presentation Transcript

  1. Distinguishing betweenorganic compounds • Organic substances can look the same – you must be able to distinguish between common compounds by comparing their properties and performing simple tests. 12 Chemistry 2.2 organic chemistry CR 07

  2. Common compounds • Alcohols, carboxylic acids, alkanes, alkenes, esters • - all colourless liquids! • How could you distinguish between them?? 12 Chemistry 2.2 organic chemistry CR 07

  3. Alcohols, carboxylic acids, alkanes, alkenes, esters • Questions you could ask: • Is it flammable? • Is it miscible with water? • Does it react with an oxidant? • Does it react with halogens? • Does it smell? • Does it behave as an acid? 12 Chemistry 2.2 organic chemistry CR 07

  4. Alcohols, carboxylic acids, alkanes, alkenes, esters • Mix with water 12 Chemistry 2.2 organic chemistry CR 07

  5. Alcohols, carboxylic acids, alkanes, alkenes, esters • Add magnesium 12 Chemistry 2.2 organic chemistry CR 07

  6. Alcohols, carboxylic acids, alkanes, alkenes, esters • Add Br2 clear 12 Chemistry 2.2 organic chemistry CR 07

  7. Alcohols, carboxylic acids, alkanes, alkenes, esters • Add Cr2O72-/H+ 12 Chemistry 2.2 organic chemistry CR 07

  8. Alcohols, carboxylic acids, alkanes, alkenes, esters • Carefully smell 12 Chemistry 2.2 organic chemistry CR 07

  9. Alcohols, carboxylic acids, alkanes, alkenes, esters • Carefully ignite – not necessary as other tests will identify them 12 Chemistry 2.2 organic chemistry CR 07
