Fermentation of carbohydrates is a source of

1. ethanol

2. MTBE

3. methanol

4. ethers

I am working on self test in the book, but the answer is not in the back of the book for this. Any help??

Didn't the bootleggers make ethanol with sugar.

To determine the correct answer to this question, we need to understand the process of fermentation and its products. Here are some steps you can follow to find the answer:

1. Understand the concept of fermentation: Fermentation is a metabolic process in which microorganisms, such as bacteria or yeast, convert carbohydrates into simpler compounds in the absence of oxygen.

2. Assess the products of carbohydrate fermentation: During fermentation, one common product is ethanol, an alcohol that is often used as a biofuel or in alcoholic beverages. Other alcohols, such as methanol, can also be produced, but they are generally less common.

3. Eliminate irrelevant options: From the given list, we can eliminate options 2 and 4, as MTBE (Methyl tert-butyl ether) and ethers are not typically produced during fermentation.

4. Identify the correct answer: Based on the information gathered, we can conclude that the correct answer to the question is option 1: ethanol.

Remember, self-tests in books may occasionally have errors or omissions. In such cases, it's best to rely on your understanding of the concept and reference other reliable sources to confirm the answer.
