Combustion of an Aromatic Series

In this portion of the lab you will consider three compounds with decreasing amounts of aromaticity in the naphthalene series shown below:



naphthalene



tetralin or tetrahydronaphthalene



decalin or decahydronaphthalene

  • Weigh out approximately 0.7 g of each sample. Weigh accurately to +/- 0.1 g.
  • Follow the general combustion procedure using the compounds from the series above. Take temperature vs. time measurements.
  • You will be comparing the heat of combustion for these samples and looking at differences that arise as a result of the amount of aromaticity.
