A series of monochloro-o-methylated biphenyls was photolysed.Quantum yields of dechlorination lie in between the low values observed for 3- and 4-chlorobiphenyl and the high values obtained for 2-chlorobiphenyl.The results are interpreted in terms of raising the energy of the excited state due to steric crowding of the ortho-substituent and relief of strain upon the departure of an ortho-chlorine.
