You will react the alcohols with purple KMnOs and and can observe if the reaction occurs by the disappearance of the purple colour (same type of reaction from the Rate Law lab doen earlier in the semester). Read the note found in the course website (stream) and then summarizelexplain how time and colour may also be used to help identify the type of alcohol. ry or tertiary) can be determined by testing to see if acid (2 marks) 3.
