To the chemical, properties for Lucas Test it is expected that alcohols and phenols react as follows: Lucas, reagent is a mixture of zinc chloride in HCl concentradi oir ki that a tertiary alcohol reacts, quickly and immediately gives an insoluble white layer. Aromatic heterocycles. Discussion: Several Tests were done on the samples: 1-butanol, 2-butanol, 2-methyl-2-propanol, phenol and an unknown to identify which are alcohols and phenols and differentiate them from one another. In a phenol, the OH group is connected to a carbon on a benzene ring where as in alcohols, the OH group is connected to a sp3 hybridized carbon atom.
