Pinnacole rearrangement

A breathalyzer test is used to detect drunken drivers. The crystals used will change colour, from orange to dark green, if ethanol vapour is detected. Explain the colour change and give a suitable equation for the reaction.

Yeast is a unicellular organism, which can break glucose down anaerobically (without oxygen). Discuss with suitable equations how yeast can be used to produce ethanol, wine and rum.
