Br: SÖH - Sy2 a. Rate - k[A]2 b.Rate = K[A][B] c. Rate -k[A] d. Rate = k[B]? e. Rate = k[B] QUESTION 59 Which of the following is the repeat unit for the polymer produced in the following reaction? ROOR A. II B. III Ос. м DI

Answer 1

Question 46 for E2 elimination we need a beta hydrogen atom with respect to the leaving group, which is only present in the the compound III Н Br three hydrogens are there, two green are equivalent, and the blue one is differnt Major product /saytzev's product is obtaimed when the base NH2 takes the blue proton and the minor product is obtained hen the base takes any of the green hydrogen Br Major product NH2 ΣΗ minor product Answe is III

Question 55 Br: OH SN For the SNP reaction the rate of the reaction is depends on both the substrate as well as the nucleophoile that is SNP is a bimolecular reaction hence the rate law for the reaction is given by rate = K[A][B]

Question 59 ROOR Poly Vinyl Chloride PVC Hence the repeat unit for the polymer is option II
