MCQ
How can ethene be produced from ethanol
- ABy dehydrohalogenation
- BBy dehydrogenation
- ✓By dehydration with conc. ${H_2}S{O_4}$ at ${170\,^o}C$
- DBy reduction with hydrogen iodide
The reaction of ethene with steam to form ethanol can be reversed. This allows ethanol to be converted into ethene. This is called a dehydration reaction.
$\underset{Ethanol}{C _2 H _5 OH} \xrightarrow[160^{\circ}-170^{\circ} C]{Conc. H _2 SO _4} \underset{Ethene}{CH _2= CH _2}+ \underset{Water}{H _2 O}$
