Question

Introduction to Sul and 52 Reactions Alkyl Halides, RX, can undergo substitution reaction. These reactions are described as a reaction between an electrophile and a nucleophile. The generk equation for these reactions Nu + R-X - - R-Nu + X 2. Merent rate laws and mechanisms describe There are two types of substitution reactions, Seland them. 5.1 Unimolecular substitution reaction ratek [RXI 52 Bimolecular Substitution reaction ratek TRXIN] Mechanisms L Complete the 5.2 reaction by adding the curved arrows, transition state, and productor products (Mechanism 9.1 in your text walks you through this example following u nd 1) this diagram constant with the rate law? Why or why not? 2) Which bands are breaking of forming is the transition state? 3 Experimental evidence shows that tertiary all thalides react the slowest and primary alkyl haldes react the fastest with nucleophiles in this reaction. Explain why this is content with the reaction diagramin 9.1. II) Complete the Sul reaction by adding the curved arrows, intermediate, and product our products IMechanium 9.2 in your text walk you through this ample) ngôi-

Answer 1

1) the mechanism is consistent with the rate law as the only step involves both OH- and the substrate .

PU5) La a) ① YES Rate law = k YES The Rate law = klok ? Penal which are involved in ROS C- By bond is breaking cooH bond is forming & CH₂OH + Cung Br Slow He ta Planas Carboraron tema- Сми

2) The C-Br bond is breaking and C-OH bond is forming.

3) The rate of SN2 reactions decrease from primary to secondary to tertiary , as the nucelophile has to attack from back side of the tetrahedral carbon, and if the H are replaced by bulky alkyl groups the appraoch for nucleophile is difficult , thus the rate of reaction decreases.
