What is the Lucas test?
Tertiary alcohols react and show a __ almost instantly because they form relatively stable __. Secondary alcohols react in about 1 to 5 minutes because their secondary carbocations are less stable than tertiary ones. Primary alcohols react very slowly. Since the activated primary alcohol cannot form a __, it simply remains in solution until it is attacked by the chloride ion. With a primary alcohol, the reaction may take from ten minutes to several days
