Ethanol reacts with excess acidified K\(_2\)Cr\(_2\)O\(_7\) to produce

  • ethanedioic acid
  • ethanal
  • ethylethanoate
  • ethanoic acid checkmark

The correct answer is: D

Explanation

When ethanol reacts with excess acidified potassium dichromate, it produces ethanoic. This reaction occurs in two steps: 

  1. Ethanol to ethanal: Ethanol is oxidized to ethanal.
  2. Ethanal to ethanoic acid: Ethanal is oxidized to ethanoic acid.Potassium dichromate is a strong oxidizing agent. During the reaction, the color changes from orange to green.
