5. Write one example each to illustrate the following:
(i) Fermentation (ii) Esterification
Answers
Fermentation;
Lactic acid fermentation. Yeast strains and bacteria convert starches or sugars into lactic acid, requiring no heat in preparation. ...
Ethanol fermentation/alcohol fermentation. ...
Acetic acid fermentation.
Esterification:
As a specific example of an esterification reaction, butyl acetate can be made from acetic acid and 1-butanol.
