I have a unknown sample of an alcohol (ceric nitrate positive) but when I did chromic acid test it was negative since it never turned into blue/green and against all odds iodoform was positive... yellow precipitate and a lot...
I have no clues of how to make sense into this. So I did lucas test as well but noticed later that it didn't help because my sample is not very soluble in water.
Judging by the great amount of precipitate I got from the iodoform test, I'm thinking that maybe my sample is indeed a primary or secondary alcohol but it has something that won't react with the chromic acid. Are there any considerations to account for when doing this test? or some limitations?
