Chromic acid and primary alcohol
WebIn organic chemistry, dilute solutions of chromic acid can be used to oxidize primary or secondary alcohols to the corresponding aldehydes and ketones. Similarly, it can also be used to oxidize an aldehyde to its corresponding carboxylic acid. Tertiary alcohols and ketones are unaffected. http://myweb.liu.edu/~swatson/downloads/files/Experiment_6.pdf
