Why are most organic compounds decompose easily under heat?

Most organic compounds decompose easily under heat because they contain carbon-based molecular structures that are held together by relatively weak covalent bonds. When exposed to high temperatures, these bonds can break, leading to the breakdown of the compound into simpler molecules or elemental forms. Additionally, the presence of functional groups in organic compounds can make them more susceptible to thermal degradation. This process often results in the release of gases and other products, reflecting the instability of organic molecules under heat.
