An alcohol that can be prepared by fermentation is:
Correct answer: C. CH3-CH2-OH
- A. CH3OH
- B. C3H7OH
- C. CH3-CH2-OH
- D. C6H5OH
Explanation
Ethanol (C2H5OH) is indeed an alcohol that can be prepared by fermentation.Fermentation is a metabolic process in which sugars such as glucose, fructose, or sucrose are converted into ethanol and carbon dioxide by the action of yeast or bacteria in the absence of oxygen. Yeasts, particularly Saccharomyces cerevisiae, are commonly used in the fermentation of sugars to produce ethanol.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
