how to test for ethanol chemistry

It is based on the appearance of brisk effervescence due to the liberation of hydrogen gas when alcohol reacts with active metals like sodium. 232, Block C-3, Janakpuri, New Delhi, Give the equations of reaction for the preparation of phenol from cumene. Tertiary alcohols reacts immediately and give cloudiness, secondary alcohols reacts slowly and gives cloudiness after 5 to 10 minutes and there is no reaction with primary alcohols. Filter the solution. The general formula for alcohol is R-OH. The hot mixture is poured into a beaker containing cold water. Which type of alcohol is present in beer, wine and vodka? Use the thermometer to make sure that the temperature of the sample you are testing is 68 degrees F. Pour 100 millimeters of your test sample into the measuring cylinder, and let it stand for a while. Add 1gm of anhydrous calcium sulfate and shake well to remove excess water. Phenol can easily lose ion because the formed phenoxide ion is somewhat stabilized by resonance. Alcohol or reaction with ceric ammonium nitrate forms a pink or red colour precipitate due to the formation of a complex compound and ammonium nitrate. Add 25 drops of iodine solution to each alcohol. Methanol and ethanol can be distinguished by using iodoform test. Which is the most sustainable way to make ethanol?
