Why are organic solvents flammable?
Their high flammability is the result of their ease of reaction with oxygen, and the large amount of heat given out when they react. This heat results from the formation the bonds in CO2 and H2O, which are very stable and have less energy than the bonds of the initial reactants. The excess energy is lost as heat.
