Reaction of Complete Oxidation

The reaction of complete oxidation involves the conversion of a substance into its fully oxidized form, typically resulting in the formation of carbon dioxide (CO2) and water (H2O). Let's analyze the given options to identify the reaction of complete oxidation:

a) 2CH3COOH + Na2CO3 → 2CH3COONa + CO2 + H2O This equation represents the reaction between acetic acid (CH3COOH) and sodium carbonate (Na2CO3). However, this is not an example of complete oxidation. It is a neutralization reaction where acetic acid reacts with sodium carbonate to form sodium acetate, carbon dioxide, and water.

b) HCHO + Ag2O → HCOOH + 2Ag This equation represents the reaction between formaldehyde (HCHO) and silver oxide (Ag2O). Again, this is not an example of complete oxidation. It is a redox reaction where formaldehyde is oxidized to formic acid, and silver oxide is reduced to elemental silver.

c) 2CH3CHO + 5O2 → 4CO2 + 4H2O This equation represents the reaction between acetaldehyde (CH3CHO) and oxygen (O2). This is the correct example of complete oxidation. Acetaldehyde is fully oxidized to form carbon dioxide and water.

d) CH3CHO + H2 → C2H5OH This equation represents the reaction between acetaldehyde (CH3CHO) and hydrogen gas (H2). This is not an example of complete oxidation. It is a reduction reaction where acetaldehyde is reduced to ethanol (C2H5OH) by hydrogen gas.

Therefore, the correct answer is option c) 2CH3CHO + 5O2 → 4CO2 + 4H2O. This reaction represents the complete oxidation of acetaldehyde to form carbon dioxide and water.
