Acyl chlorides are split into acyl and chlorine radicals by light of wavelength 254 my. Since the dissociation energy of the chlorine-hydrogen bond is considerably larger than that of the acyl-hydrogen bond, substitution of the substrate by acyl radicals is observed on irradiation of acid chlorides.
