Warm and distill with acidified pottasium dichromate. Then test with tollens reagent. The acidified pottasium dichromate will have oxidised the primary alcohol to an aldehyde, which will form a silver mirror...

In Chemistry we need to know the structures of the molecules we make and work with. We use spectroscopy to work out the shapes of these molecules. Mass spectrometry is one type of spectroscopy and weighs the...
