(i) Number of H atoms abstracted by D = 5 and percentage of compound formed = 96 %
Therefore, reactivity factor for replacement of H atoms = 93/5 = 18.6
(ii) Number of D abstracted by Cl = 1 and percentage of compound formed = 7%.
Therefore, reactivity for D replacement = 7/1 = 7
(iii) Relative reactivity of H: D abstraction = 18.6/7 = 2.7: 1 , i.e. , each H is abstracted 2.7 times faster than D.
