3. how is it possible for the lucas test to give a false positive? that is, if you see a second layer of insoluble organic liquid, what could the unknown be in addition to a tertiary alcohol?

Respuesta :

The second layer of insoluble organic liquid may have the product ester along with some tertiary alcohol.

The Lucus test is necessary to distinguish between primary secondary and tertiary alcohols. The difference in reactivity of primary secondary and tertiary alcohols with hydrogen halides as determined by the SN1 reaction is used to determine the validity of this test. Tertiary alcohols react the fastest due to the relatively low solubility of organic chlorides in aqueous mixtures.

If positive, the color of the sample changes from clear to cloudy, indicating the formation of chloroalkanes. The Lucas test is performed to identify primary, secondary, and tertiary alcohols and determine which alcohol produces the fastest alkyl halide. The alcohol is soluble in the Lucas reagent, but the alkyl halide formed from the reaction is not. Thus, two layers are formed in the reaction medium.
