Making Alcohols by Fermentation & from Ethene

The video tutorial covers the uses of alcohol in products like antifreeze and hand sanitizers. It explains the fermentation process, where sugars are converted into ethanol and carbon dioxide using yeast. The tutorial also describes the production of ethanol from ethene, highlighting the use of water and phosphoric acid as a catalyst. It compares the two methods, noting that fermentation uses renewable resources and less energy, while the ethene method is faster but relies on non-renewable crude oil.

What is the primary reactant in the fermentation process to produce ethanol?

• Water

• Carbon Dioxide

• Sugar

• Yeast

Which catalyst is used in the reaction of ethene with water to produce ethanol?

• Nitric Acid

• Hydrochloric Acid

• Sulfuric Acid

• Phosphoric Acid

What is a major advantage of the ethene route over fermentation in ethanol production?

• It uses renewable resources

• It produces more waste products

• It requires less energy

• It is faster and more efficient

Why is the fermentation route considered more sustainable than the ethene route?

• It produces more carbon dioxide

• It uses renewable plant sugars

• It requires higher temperatures

• It uses non-renewable resources

What is a significant energy-related drawback of the ethene route for ethanol production?

• It does not require any heating

• It requires high temperatures for crude oil and steam

• It uses less energy than fermentation

• It requires heating to only 37 degrees
