By fermentation process of starch and by the catalytic enzyme, _ is produced.
Correct answer: B. Ethyl alcohol
- A. Methyl alcohol
- B. Ethyl alcohol
- C. Acetyl alcohol
- D. Methanal
Explanation
Starch essentially breaks down to give glucose which undergoes the process of glycolysis to give pyruvate and NADH alongside ATP. Pyruvate undergoes decarboxylation to give ethanal and ethanal is reduced by NADH to give ethanol which is an ethyl alcohol. This is, basically, the summarization of the alcohol fermentation so the answer is B.

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.
