1. (a) Because the reaction is an addition reaction there are no other products formed so all the reactants are converted into the desired product.(b) Mass of 1000 H2N(CH2)6 NH2 = 1000 x 116.04 = 116040 gMass of 1000 ClOC(CH2)4COCl = 1000 x 183.04 = 183040 gTotal mass of reactants = 299080 gMass of H−[HN(CH2)6NHCO(CH2)4CO]1000−Cl = 299080 – 1999 x M(HCl) = 299080 – 72864 = 226216 gOnly 90% yield so mass of desired...
