The general purpose of this project has been to obtain a knowledge about the reaction of para-benzoquinone when irradiated with ultraviolet light in water or ethanol. The 1, 4, benzoquinone, often called simply quinone, is a yellow crystalline solid melting at 116°C and having a sharp penetrating odor. Quinone shows a marked increase in reactivity when it is irradiated with U.V. A possible explanation for this could be that the electrons in central carbon atoms of the quinone absorb quanta of energy. The resulting excited state could then leas to a free radical formation. This could account for the increased reactivity.
