Which process involves the breakdown of larger organic molecules into smaller molecules by the action of heat in the absence of oxygen?

A. Combustion
B. Pyrolysis✓ Correct Answer
C. Hydrolysis
D. Neutralization

💡 Solution & Explanation

Pyrolysis is the thermal decomposition of carbon-based materials at elevated temperatures in the complete absence of oxygen, preventing combustion and altering chemical structures. Combustion requires oxygen to release energy, whereas hydrolysis uses water to break chemical bonds.
