The conversion of ethanol to ethanoic acid is an example of which of the following reactions?

Correct option is B

The correct answer is (b) Oxidation reaction

• ​The conversion of ethanol $$(C_2H_5OH)$$ to ethanoic acid $$(CH_3COOH)$$

Explanation:

Ethanol $$(C_2H_5OH)$$ undergoes oxidation in the presence of an oxidizing agent (such as potassium dichromate$$(K_2Cr_2O_7)$$

​​in acidic medium or oxygen in the presence of a catalyst)

The hydroxyl group (-OH) in ethanol is oxidized, leading to the formation of an aldehyde (ethanal, ($$CH_3CHO$$), which is further oxidized to ethanoic acid ($$CH_3COOH$$)

Reaction:

Oxidation of ethanol to ethanal:

​$$C_2H_5OH+[O] →CH_3CHO+H_2O$$

​​Oxidation of ethanal to ethanoic acid:

​$$CH_3CHO+[O] → CH_3COOH$$​​

Final Reaction:

​$$C_2H_5OH +2[O] → CH_3COOH + H_2O$$

​​the reaction is classified as an oxidation reaction.​

Addition Reaction

• An addition reaction is a type of chemical reaction where two or more atoms or molecules combine to form a single product.
• This typically occurs in compounds with double bonds or triple bonds, such as alkenes and alkynes, where the multiple bonds break to accommodate the new atoms.

​Combustion Reaction:

• A combustion reaction is a chemical reaction in which a substance (typically a hydrocarbon or organic compound) reacts with oxygen ($$O_2$$) to produce energy in the form of heat and light. Combustion is an exothermic reaction.
  

Substitution Reaction:

• A substitution reaction is a chemical reaction in which one atom or group of atoms in a molecule is replaced (substituted) by another atom or group. These reactions are common in organic and inorganic chemistry.
