Primary alcohols react slowly and secondary alcohols react rapidly.
To generate comparison data for primary and secondary alcohols, tests should be first carried out using ethanol and 2-propanol. After noting the time, flick the test tube with your finger several times to mix the contents. Watch the test tube until a precipitate forms and record the elapsed time. The elapsed time could range from a few seconds to a few minutes. Do not get the solution on your clothes, your skin, or any lab surfaces.
