When evaluating a chemical's potential for explosion, which intrinsic property, beyond simple flammability, signifies an unstable molecular structure prone to rapid decomposition and energy release?

The intrinsic property that signifies an unstable molecular structure prone to rapid decomposition and energy release, beyond simple flammability, is its heat of decomposition. Flammability refers to a substance's ability to burn or ignite easily, requiring an external ignition source and oxygen. Explosives, however, possess an inherent instability that allows them to decompose very rapidly, releasing a large amount of energy and gas without needing external oxygen. This rapid decomposition is the core of an explosion. Heat of decomposition is the amount of energy (heat) released when a substance breaks....
