This video explores the ins and outs of alcohol combustion, as well as a simple experiment that could be used to reliably compare the enthalpy of combustion for a range of alcohols.
00:00 Combustion of Alcohols
03:46 Measuring and Comparing ∆H of Alcohols
● explain the properties within and between the homologous series of alcohols with reference to the intermolecular and intramolecular bonding present
- boiling and melting point
- solubility in water
- molar enthalpy of combustion
● conduct a practical investigation to measure and reliably compare the enthalpy of combustion for a range of alcohols
Why do combustion of alcohols produce heat? Why are they exothermic? Why do larger alcohols release more energy? How do we measure an alcohol's heat of combustion or enthalpy change?
