alleryHow can ethanol be converted to ethene?
ABy heating with sodium
BBy burning in oxygen across all cases
CBy heating with concentrated H2SO4 at about 443 K
DBy reacting with KMnO4
Answer & Solution
Correct answer: C. By heating with concentrated H2SO4 at about 443 K
1. Removing one H2O molecule from ethanol gives ethene.
2. Concentrated H2SO4 is a strong dehydrating agent.
3. Heating ethanol with conc. H2SO4 at about 443 K removes water.
4. The product is ethene (CH2=CH2).
5. So option A is the correct method.
