Comparing the Chemical Properties of Alkanes and Alkenes Aim To investigate and compare the chemical properties (notably the reactivity) of the alkane Cyclohexane and the alkene Cyclohexene. Hypothesis Based on previous knowledge of alkanes and alkenes I suggest the chemical properties of the two will be similar as both are fuels, however, as alkenes (but not alkanes) contain a carbon double bond (C=C) some of the chemical properties will differ. Method Apparatus: * Hard glass watch glass * Wood splints * 10 dry test tubes (two of which covered in aluminium foil) * 10 tight fitting bungs (to seal the test tubes) * Test tube rack * Bromine dissolved in an inert solvent (Bromine Water) * Acidified Potassium Manganate (VII) solution * Concentrated Sulphuric acid (H2SO4) Procedure A: Combustion 1. Place 3-4 drops of cyclohexane onto the watch glass 2. Light a splint and use this to light the cyclohexane 3. Record observations (e.g. Colour of the flame, amount of soot produced) Procedure...
