Correct Answer: Option 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

There is an explanation video available below.
