Methylpropan-2-ol is a tertiary alcohol and when shaken with Lucas reagent (ie:do the lucas test on it) a cloudy solution layer forms very quickly (cos its a tertiary alcohol) But why is it cloudy???
I know an alkyl halide has formed but why is it cloudy???
Please respond quickly! Jen

The t-butyl chloride that is formed in the reaction is insoluble in the alcohol.
(CH3)3COH + HCl ----> (CH3)3CCl + H2O

The alkyl halide is insoluble in the water that is produced by the reaction of the OH group on the alcohol with the hydrogen in the acid, hence it precipitates out to form the cloudiness you observe
