lucas reagent is the mixture of anhydrous zncl4 with a conc hcl acid
 
 
when the reagent reacted with 1 degree 2 degree and 3 degree alcohol the following results are seen this is known as the lucus reaget test the alcohol can be distinguidhed by this test as follows
 
1^0alc =lucas reagent---> no turbidity formed(turbidity can be formed after heating)
 
 
2^0 alc.+ lucas reagent ---->.turbidity formed after 10-5 minuts 
 
3^0alc.+lucas reagent----->turbidity formed immediately

Lucas reagent is anhydrous ZnCl2 and con HCI
primary alcohols does not form turbidity at room temperature . turbidity is obtained on heating
secondary alcohols form turbidity in 5 to 10 minutes. tertiary alcohols from turbidity immediately.
