xplain the predicted value of the Bond dissociation Energy.
Žo C (PAMS) In the table below the dissociation energies are given for the bonds in bold of the a- methylstyrene (AMS) dimers D, E and F below. Note: these dimers are model compounds for head-to-tail (H-T), head-to-head (H-H) and tail-to-tail (T-T) linkages in PAMS. Dimer structure D E F Bond dissociation energy (kJ/mol) (bond in bold) 405 461 330 a) Show how each the linkages H-T, H-H and T-T is formed during the polymerization of AMS using mechanistic diagrams and deduce which model compound (D, E, or F) relates to each linkage (i.e., H-T, H-H and T-T) observed in PAMS. b) Building upon your assignments from (a), explain the predicted values for the bond dissociation energies for the bonds in bold for the model compounds D, E and F. In your answer make sure to provide reaction mechanisms and comment on the relative stability of the radical species formed during homolysis.
