What are fatty alcohols derived from?

  1. Synthetic chemicals

  2. Fatty acids exposed to hydrogen

  3. Natural mineral sources

  4. Alcohol fermentation

The correct answer is: Fatty acids exposed to hydrogen

Fatty alcohols are derived from fatty acids exposed to hydrogen due to a process called hydrogenation. This process adds hydrogen atoms to unsaturated fatty acids, transforming them into saturated fatty acids, which can then be converted into fatty alcohols. Option A is incorrect because fatty alcohols are derived from natural fatty acids, not synthetic chemicals. Option C is incorrect because fatty alcohols are not derived from natural mineral sources such as rocks or ores. Option D is incorrect because alcohol fermentation produces ethyl alcohol, not fatty alcohols.
