Planning: Aim: To try to work out the bond energies of the alcohols in the homologous series up to Pentanol, comparing them to the data book values. There are a few factors in these experiments that will affect our enthalpies (as opposed to the data book values), which will be outlined later on in the write-up. Equipment: An alcohol burner - This is the heat provider. Heat proof mats - To insulate heat. A stand + clamps - To support the experiment structurally. A thermometer - To discern the starting and finishing temperatures. 50ml of water - Substance to be heated. A copper can - Metal conductor of heat. Electronic scales - To weigh the burners. A measuring cylinder - To measure out the correct volume of water accurately. Hypothesis: I predict that the enthalpies of the alcohols will decrease as the number of carbons increases. The results should reflect the text book values to some extent and show a correlation...
