NEETChemistryAlcohols Phenols and Ethers
What is the mechanism of acid dehydration of ethanol to yield ethene?
Options
- AProtonation of ethanol, followed by loss of water to form an ethene carbocation, and deprotonation to yield et
- BElectrophilic attack of ethanol on a strong acid, leading to the formation of an ethene intermediate.
- CNucleophilic substitution of ethanol with a strong acid, leading to the formation of ethene.
- DOxidation of ethanol with a strong acid to directly yield ethene.
Correct answer
A. Protonation of ethanol, followed by loss of water to form an ethene carbocation, and deprotonation to yield et
Step-by-step solution
Correct Option is : (A) Protonation of ethanol, followed by loss of water to form an ethene carbocation, and deprotonation to yield ethene.
