Question

How is ethanol converted into ethene using (1) solid dehydrating agent (2) hot conc. H2SO4 ? Give only balanced equation .

Answer 1

1): a solid dehydrating agent

C2h5oh ----al2o3---> c2h4 +h20

2): using h2so4

C2h50h ----h2so4----> c2h4+h20

170℃

Hope it helps!!!!

Answer 2

Ethene production from ethanol

1. From solid dehydrating agent:

• $Al_2O_3$ is a solid dehydrating agent.

• At 300°С in presence of $Al_2O_3$ as catalyst, ethanol gets converted into ethene and water.
• The balanced chemical equation involved in the reaction is as follows:

$C_2H_5OH\rightarrow C_2H_4+H_2O$

2. From Concentrated Sulfuric acid:

• When ethanol is heated at 170°С, in the presence of Conc. Sulfuric acid as catalyst, it gets converted into ethene.
• The balanced chemical equation involved in the reaction as follows:

$C_2H_5OH + H_2SO_4\rightarrow C_2H_4+H_2O$
