a) For the above given graphs, the endothermic reaction represents the transition state close to the product and hence the structure of the product will likely to resemble that of product as per the Hammond postulate. Hammond's postulate states that the transition state of a reaction resembles either the reactants or the products, to whichever it is closer in energy. b) The propagation step is exothermic. Since the propagation step is so exothermic, it occurs very quickly and follows Le Chatelier's principle Hence, the exothermic curve will represent the rate determining step. Bromination of butane. 2-bromobutane, the red arrow represents the chiral center and this isomer is an enantiomer. 1- bromobutane has no chiral center. The 2-bromobutane is the major product because it will form a secondary radical during the course of the reaction.
