1. How is ethene prepared from ethanol? Give the reaction involved in it.
When ethanol is heated with excess concentrated (at 443 K), it produces ethene. The following equation can show this.
\(CH_3CH_2OH + hot conc. H_2SO_4 \xrightarrow[]{at- 443K} H_2C = CH_2 + H_2O\)
Concentrated phosphoric acid, \(H_3PO_4\), can be used instead of concentrated sulphuric acid.
of ethanol takes place in this reaction.
2. Intake of small quantity of methanol can be lethal. Comment.
If methanol is taken in huge quantities, it converts into or formaldehyde. This substance coagulates the cells of the body and blocks the , thus causing blindness. It is toxic and cancer-causing too. It is naturally present in small quantities in fruits and the human body.
