Answer to Question #161142 in Organic Chemistry for sabi

Question

. If you were given 2 test tubes and were told that one was heptan-1-ol and other was heptan-2-ol ,describe two tests that you could run on the samples to identify them

Answer 1

heptanol -1 is a primary alcohol, heptanol -2 is a secondary one.

1) It is necessary to add Lucas's reagent (concentrated hydrochloric acid with zinc chloride) to each test tube, after five minutes the solution in the test tube with secondary alcohol will become cloudy, the primary alcohol will not react in any way.

2) Add Corey reagent to each tube, wait, then add Fehling's solution. An orange or yellow precipitate will appear in the test tube with primary alcohol.
