Question

It’s known to be used in Egypt in 3000 BC, but its name had been derived from an old French expression. It is made from the fermentation of ethanol in a process that yields its key ingredient, ethanoic acid. What is it?

• A. Tabasco Sauce
• B. Phenol
• C. Vinegar
• D. Soya Sauce

Answer 1

The Correct Option is C

To determine the correct answer, consider the details provided: The key components are the historical use in Egypt around 3000 BC, the derivation of its name from an old French expression, and its production through the fermentation of ethanol resulting in ethanoic acid. These clues are crucial for identifying the correct answer.

The process described involves fermentation, a common method to produce vinegar, where ethanol is converted into ethanoic acid, also known as acetic acid, the main component of vinegar. The term 'vinegar' is indeed derived from the old French 'vinaigre', meaning 'sour wine'.

Given this information, the options can be examined:

1. Tabasco Sauce

2. Phenol

3. Vinegar

4. Soya Sauce

Among these options, only vinegar fits all the discussed criteria: historical usage, name derivation, and production method involving ethanoic acid. Hence, the correct answer is Vinegar.
