QUESTION:
Problem 19P
Propose mechanisms to show the interchange of protons between ethanol molecules under
(a) acid catalysis (b) base catalysis
ANSWER:
Solution:
Here we have to propose mechanisms to show the interchange of protons between ethanol molecules under (a) acid catalysis (b) base catalysis
Step 1
(a)Acid catalysis with ethanol:-
Ethanol has been protonated when it undergoes acid catalyzed reaction and forms CH3-CH2-H2O+ , which on addition with the anion further undergoes deprotonation and forms ethanol.
