Making Alcohols By Fermentation & From Ethane

The video tutorial covers the uses of alcohols, focusing on ethanol in alcoholic drinks and its production methods. It explains fermentation, where sugars from plants are converted into ethanol and carbon dioxide using yeast. The video also describes an alternative method of producing ethanol from ethene, highlighting the efficiency and drawbacks of each method. The fermentation process is renewable but slower, while the ethene route is faster but relies on nonrenewable resources and requires more energy.

What is the primary role of yeast in the fermentation process?

• To produce carbon dioxide

• To balance the chemical equation

• To act as a catalyst

• To provide sugar for the reaction

Which molecule is added to ethene to produce ethanol in the industrial process?

• Oxygen

• Nitrogen

• Water

• Carbon dioxide

What catalyst is used in the reaction between ethene and water to produce ethanol?

• Hydrochloric acid

• Acetic acid

• Phosphoric acid

• Sulfuric acid

Why is the ethene route considered more efficient than fermentation?

• It has no waste products

• It requires less energy

• It produces more ethanol

• It uses renewable resources

Which of the following is a renewable resource used in ethanol production?

• Natural gas

• Coal

• Crude oil

• Plant sugars
