What tests can you do to tell the difference between a primay seconday and tertiary alcohol?

To differentiate between primary, secondary, and tertiary alcohols, you can use the Lucas test, which involves adding Lucas reagent (a mixture of zinc chloride and hydrochloric acid) to the alcohol. Primary alcohols react slowly, secondary alcohols react moderately, and tertiary alcohols react rapidly, forming an immiscible layer. Another method is the oxidation test; primary alcohols oxidize to aldehydes, secondary alcohols to ketones, and tertiary alcohols do not oxidize easily. Additionally, infrared spectroscopy can help identify functional groups associated with each type of alcohol.
