Chemists have found that chromium (VI) in a chromium trioxide dipyridine complex (CrO3-2Py) can be used to selectively oxidize a primary alcohol to an aldehyde without further oxidizing the aldehyde to an acid. An additional benefit is that double bonds are not oxidized either. 6. Write a balanced half reaction for the oxidation of cinnamyl alcohol, C6H5CH-CHCH2OH to cinnamaldehyde, C6H5CH=CHCHO Write a balanced half reaction for the reduction of chromium trioxide to chromium (III) Write the overall balanced reaction for...
