Complete the following equation: CH 3 CH 2 OH → 170 ° C Conc . H 2 SO 4

CH 3 CH 2 OH ( Ethanol ) → 170 ° C Conc . H 2 SO 4 CH 2 = CH 2 ( Ethene ) + H 2 O Ethanol undergoes dehydration reaction in the presence of concentrated sulphuric acid to produce ethene. Here, the acid serves as a catalyst for the reaction.

Complete the following equation: CH 3 OH + C 2 H 5 OH → Conc . H 2 SO 4

CH 3 COOH ( Ethanoic acid ) + C 2 H 5 OH ( Ethanol ) → Conc . H 2 SO 4 CH 3 COOC 2 H 5 ( Ethyl ethanaoate ) + H 2 O Water Ethanol and ethanoic acid, in the presence of concentrated sulphuric acid reacts to form ethyl ethanoate. It is an esterification reaction. Here, the sulphuric acid acts as a catalyst in the reaction.
