Here's the information regarding the preparation of ethanol: Preparation of Ethanol from Ethene via Ethyl Hydrogen Tetraoxosulphate (VI): Step 1: Ethene reacts with concentrated tetraoxosulphate (VI) acid to form ethyl hydrogen tetraoxosulphate (VI). C_2H_4(g) + H_2SO_4(aq) C_2H_5HSO_4(aq) Step 2: The product, ethyl hydrogen tetraoxosulphate (VI), is diluted with water and boiled to yield ethanol and regenerate tetraoxosulphate (VI) acid, which can be reused. C_2H_5HSO_4(aq) + H_2O_(l) C_2H_5OH_(aq) + H_2SO_4 Other Methods of Preparing Ethanol in the Laboratory: 1. By hydration: Ethene is mixed with steam in the presence of H_2SO_4 as a catalyst at 600^ and 80 atm. C_2H_4(g) + H_2O_(g) 600^, 80 atm, H_2SO_4 C_2H_5OH_(aq) 2. Reducing of ethanal: Ethanal is reduced using nascent hydrogen in the presence of a nickel catalyst. CH_3CHO_(g) + H_2(g) C_2H_5OH_(aq) 3. By hydrolysis of iodoethane: Iodoethane undergoes hydrolysis using alkalis. C_2H_5I_(l) + NaOH_(aq) C_2H_5OH_(aq) + NaI_(s) 4. By hydrolysis of esters: Esters are hydrolyzed using hot alkalis. CH_3COOC_2H_5(aq) + NaOH_(aq) C_2H_5OH_(aq) + CH_3COONa_(s) Industrial Preparation of Ethanol: Ethanol is produced commercially by a process involving the breaking down or slow decomposition of complex organic matter.
