Title : Reaction Of Alcohol
Objectives :
1. To classify alcohol
2. To study the chemical properties of alcohols
Introduction:
Alcohol is a class of organic compound containing hydroxyl group, OH as the functional group. Alcohol can be classified as:
H H H | | | R ̶ C ̶ OH R ̶ C ̶ OH R ̶ C ̶ OH | | | H R R
Primary Alcohol(1 ̊) Secondary Alcohol(2 ̊) Tertiary Alcohol(3 ̊)
Lucas reagent, a mixture of concentrated hydrochloric acid and anhydrous zinc chloride, can be used to differentiate the three classes of alcohols. Tertiary alcohol turns cloudy or appears in two layers almost immediately, secondary alcohol reacts within 5 to 10 minutes whereas primary alcohol reacts very slowly.
Alcohol can be oxidised to aldehyde, ketone or carboxylic acid. The product formed depends on the class of alcohol used. Various oxidising agents such as KMnO₄, Na₂Cr₂O₇ and H₂CrO₄ can be used. The reaction between alcohols and carboxylic acids will produce esters.
Apparatus:
Stopper, dropper, test tube, stopwatch, water bath, measuring cylinder (10ml)
Chemical Reagents:
Ethanol, n-Butanol, 2-Butanol, Alcohol X, Lucas reagent, 2-methyl-2-propanol, Concentrated H₂SO₄, 0.04 M Na₂Cr₂O₇, Glacial acetic acid
