The conditions necessary for the extraction of a water molecule from two molecules of ethanol are
- less acid and lower temperature
- excess acid and a lower temperature
-
excess acid and a higher temperature
- less acid and a higher temperature
The correct answer is: C
Explanation
The conditions necessary for extracting a water molecule from two ethanol molecules are:
- Concentrated sulfuric acid: The reaction requires concentrated sulfuric acid.
- Temperature: The reaction requires a temperature of 140°C.
- Excess ethanol: The reaction requires excess ethanol. The reaction that extracts a water molecule from two ethanol molecules is called dehydration, and it produces diethyl ether and a water molecule. Two ethanol molecules can also be dehydrated to form diethyl ether and a water molecule. This reaction also requires a high temperature, such as 140°C, and concentrated sulfuric acid.
- The correct answer then is excess acid and a higher temperature. - Option C
