can someone pleasee answer these 3 with an explanation 4. Propose the mechanism for this reaction:...
Propose a mechanism from the reaction in the box NaOH H,CH2CH.CH DMF Use the reaction for 28-32 28. What is the classification of the alkyl halide? a.) methyl b.) 1° c.) 2° d.) 30 29. Is the base strong or weak? a.) Strong b.) Weak 30. Is the solvent protic or aprotic? a.) Protic b.) Aprotic 31. According to the base and solvent, which substitution mechanism will the reaction undergo? a.) SNI b.) SN2 32. The stereochemistry of the reactant...
8) Draw a mechanism with all the proper arrows for the reaction from this experiment. Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both...
can someone show me how to do the work and explain it to me 12. Which of the following does not correctly describe Sn2 reactions of alkyl halides? Tertiary halides react faster than secondary halides. Rate of reaction depends on the concentrations of both the alkyl halide and the nucleophile. The mechanism consists of a single step with no intermediates. The transition state species has a pentavalent carbon atom.
5) (marks = 3) Please answer the following as TRUE or FALSE in the space provided to the left of each statement (0.5 marks each). True/False All tertiary alkyl halides only participate in SN 1 reactions. CH30 is a better nucleophile for an SN2 reaction than CH3S when in methanol. The relative stability of carbanions is as follows: (most stable) 1° >2 > 30 (least stable) Unlike other alkyl halides (CI, Br, 1), alkyl fluorides do not participate in substitution...
4) Can you ever have only SN2 or only SN1? Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both electrons of its bond to...
need help with the boxed bullet point. writing the chemical reaction scheme for the experiment. Synthesis of an Alkyl Halide: A Nucleophilic Substitution Reaction, Part I Pre-lab Assignment for Synthesis of an Alkyl Halide: A Nucleophilic Substitution Reaction, Part 1 1.

We begin with the surmise that the nucleophilic substitution reactions can occur only by one of two mechanisms: Sn1 solvolysis: three-step mechanism R-X slow, R® + to R® + ROH fast , ROM R' H. R-O + R'OH fast , ROR' + R- SN2: one-step mechanism R-X + Nuc slow, Nuc-R + x Begin by answering the three questions below. If you don't understand what's up, please ask! 1. Write out the rate law for the above Sn1 reaction and...
Show some sort of mechanism so I can understand what happens. I know H- is a nucleophile here from K+H- but I dont know what happens next. Does it deprotonate the OH making the whole ring a nucleophile to attack the alkyl halide CH3I via Sn2? 212. What would be the product of the following reaction? OH 1) KH 2) CH31
For the chemical reaction answer the following questions: 1. Is the mechanism Sn1 or Sn2? 2. What kind of substrate reacts in the following reaction? (2 ° , 2 ° allylic , 3 ° ) 3. Is the role of the alkyl halide reactant an acid, base, electrophile, nucleophile , or both a nucleophile and base? 4. Is the role of the reagent KI an acid, base, electrophile, nucleophile , or both a nucleophile and base? 5. What is the...
