- In SN2 reactions of haloalkanes, the order of reactivity is RI>RBr>RCl>RF. Alkyl iodides are considerably more reactive than alkyl fluorides, often by factors as great as 106. All 1-halo-2,4-dinitrobenzenes, however, react at approximately the same rate in nucleophilic aromatic substitutions. Account for this difference in relative reactivities.Which solvent would be the best choice (DMF, methanol, or acetic acid) to carry out the nucleophilic substitutionreaction between: bromoethane and –CN?Why a nitro group (NO2) directs electrophilic aromatic substitution tothe meta position ?
- p-Fluoronitrobenzene is more reactive toward hydroxide ion than is p-chloronitrobenzene. What does this tell you about the rate-determining step for nucleophilic aromatic substitution?i need help filling out the following SN2 reactions with appopiate reactants, products, or reagents,What is the reason an alkyne cannot be made from the following dibromide compound? A. internal alkynes have a pKa of around 26 B. a tertiary halide cannot be eliminated because of steric hindrance C. tertiary halides prefer substitution via an SN1 process D. there is no beta-hydrogen on one of the carbons that a bromine is attached to
- Can you help find the functional groups and which of these functional groups will be more reactive to nucleophilic addition?Why aryl halides are less reactive towards SN reactions as compared to alkyl halides?What contributes to the deactivating nature of halides inelectrophilic aromatic substitution? a. inductive effect b. octet rule c. delocalization of electron pair
- Arrange these compounds in increasing order of reactivity in SN2 nucleophilic substitution?In Image 4 predict the effect the substituent attached to the benzene ring would have on electrophilic aromatic substitution reactions? a.ortho/para director, deactivator b.ortho/para director, activator c.meta director, activator d.meta director, deactivatorInternal alkynes are able to selectively form one product when subjected to most reaction conditions. T or F Alkynes react with one equivalent of acid to create a carbocation for Markovnikov addition. T or F Alkynes react very similarly to alkenes. Understanding the mechanisms from chapter 12 will help understand the reaction pathways in chapter 13 where mechanisms are not explicitly drawn. T or F
