This chapter discusses some of the particular kinetic problems of hydrogen atom abstractions from O–H bonds in the context of questions of general interest. The chapter aims to make unsolved problems explicit rather than giving final solutions. It seems desirable to realize explicitly that many of the theories and treatments are entirely empirical resembling the empirical origin of the rate constant. Radicals are chemical species having a free valence in classic chemical terms, or having an electron of uncoupled spin in terms of the quantum theory. Short-lived radicals have to be continuously generated for a steady concentration to be maintained. Radical reactions are classified in different ways. Firstly they can be selected according to the phase they are studied in. This chapter deals almost entirely with liquid-phase reactions. Arrhenius parameters, the limited liquid phase data are complemented by those taken from gas phase reactions.
