Answer

  1.  
  1. Ethanol- C2H5OH/ CH3CH2OH.

 $\ \ \ \ \ \ \ \ \ \text{H}\ \ \ \ \ \ \text{H}\\\\ \\ \ \ \ \ \ \ \ \ \ \ \text{|}\ \ \ \ \ \ \ \ \text{|}\\{\text{H}-\ {\text{C}}}\ -\text{C}-\text{OH}\\\\ \ \ \ \ \ \ \ \ \ \ \text{|}\ \ \ \ \ \ \ \ \text{|}\\ \ \ \ \ \ \ \ \ \ \text{H}\ \ \ \ \ \ \text{H}$

  1. Ethanoic Acid- CH3COOH.

$\ \ \ \ \ \ \ \ \ \ \ \text{H}\\ \ \ \ \ \ \ \ \ \ \ \ \ \text{|}\\ \text{H}\ \ -\ {\text{C}}\ \ -\text{C}\ \ -\text{OH}\\\ \ \ \ \ \ \ \ \ \ \ \ |\ \ \ \ \ \ \ \ || \\\ \ \ \ \ \ \ \ \ \ \ \text{H}\ \ \ \ \ \ \ \text{O}$

  1. As oxygen is added to ethanol.

Oxidizing agent - Alkaline KMnO4 or Acidified K2Cr2O7.
