This is done in two simplified stages. First, the primary alcohol is oxidised to an aldehyde. Next, the aldehyde is converted to an acid. The alcohol is oxidised by using potassium dichromate solution in the presence of dilute sulphuric acid. It is the dichromate ion that is the oxidising agent, and dilute sulphuric acid is used to acidify the solution. Ethanoic acid process Oxidation of Ethanol Potassium dichromate solution is acidified with dilute sulphuric acid to oxidise ethanol into ethanoic acid. There are few steps that comprise this process: • Ethanol is heated under reflux with an excess mixture of potassium dichromate solution and dilute sulphuric acid. Heating under reflux is achieved by heating the mixture in a flask with a condenser placed vertically inside so that any vapour is liquefied and returned. It prevents any aldehyde that is formed from escaping before full oxidation has occurred • Excess oxidising agent is used to ensure that there is enough for the ethanol to convert to a carboxylic acid. If there was too little oxidising agent, ethanol would only partially oxidise into an aldehyde • Durin...

The formation of ethanoic acid from ethanol is oxidation reaction as: • In oxidation reaction, there is a gain of oxygen atoms and a loss of hydrogen atoms. • Also, there is a loss of electrons in oxidation reaction. • The conversion of ethanol to ethanoic acid is carried in presence of a strong oxidizing agent like potassium permanganate, and potassium dichromate. • This is an oxidation reaction as there is as addition of oxygen atom and loss of hydrogen atom.

Acidic Properties Several important chemical reactions of alcohols involve only the oxygen-hydrogen bond and leave the carbon-oxygen bond intact. An important example is salt formation with acids and bases. Alcohols, like water, are both weak bases and weak acids. The acid ionization constant \(\left( K_\text\) groups. They do this by polarization of their bonding electrons, and the bigger the group, the more polarizable it is. (Also see Basic Properties Alcohols are bases similar in strength to water and accept protons from strong acids. An example is the reaction of methanol with hydrogen bromide to give methyloxonium bromide, which is analogous to the formation of hydroxonium bromide with hydrogen bromide and water: Figure 15-4). The melting point reaches a maximum at 50-50 mole percent of each component. Nucleophilic Properties - Ether Formation Alkoxide ion formation is important as a means of generating a strong nucleophile that will readily form \(\ce2\) reactions readily. Nucleophilic Properties. Ester Formation An ester may be thought of as a carboxylic acid in which the acidic proton has been replaced by some organic group, \(\ce \right)\) at room temperature, which corresponds to \(66\%\) conversion to ester: The reaction may be driven to completion by removing the ester or water or both as they are formed.

Step 1: In the compound, Ethanol ( CH 3 CH 2 OH ) indicates the alcohol functional group present in the compound. The reaction of Ethanol with alkaline Potassium permanganate ( KMnO 4 ) solution forms an oxidized product. Step 2: The oxidation reaction of Ethanol with alkaline Potassium permanganate solution forms Ethanoic acid ( CH 3 COOH ) as the major product. The chemical equation of the conversion of Ethanol to Ethanoic acid is written as: CH 3 CH 2 OH + 2 O → alk . KMnO 4 CH 3 COOH + H 2 O ( Ethanol ) ( Oxygen ) ( Ethanoic acid ) ( Water )

The conversion of ethanol to ethanoic acid is shown below: C H 3 C H 2 O H Ethanol + O 2 → C H 3 − O ∣ ∣ C − O H Ethanoic acid + H 2 O In this reaction, a molecule of ethanol contains one oxygen atom while ethanoic acid contains two oxygen atoms. Hence, oxygen atom is added during the reaction, therefore, this conversion is an oxidation reaction.

Alkaline potassium permanganate or Acidified potassium dichromate. (i) Ethanol will not affect litmus paper. Ethanoic acid will turn blue litmus ‘ paper red. (ii) Ethanol will not react with sodium hydrogen carbonate. Ethanoic acid will give brisk effervescence due to colourless, odourless carbon dioxide gas.
