Rearrangen 3. (6) Give the mechanistic symbols (SN1, S 2, El, or E2) that are most consistent with each of the following statements. If none of them apply, write N. More than one symbol may be true for each statement (list all that apply), 1-bromopentane reacts faster than 3-bromo-2,4-dimethylpentane by this/these mechanism(s). Corresponds to the reaction profile at the right. Which mechanism gives a racemic mixture of substitution products?
For

4. Give the mechanistic symbol(s) (SNI. SN2, E1, E2) that is most consistent with each of the following statements. a. Methyl halides react with sodium cthoxide in ethanol only by this mechanism. b. Alkyl iodides react faster than alkyl bromides in reactions that proceed by these mechanisms. c. Results in the largest amount of racemization of an optically active alkyl halide. d. These reaction mechanisms are the ones mostly likely to have been involved when the products are found to...
can someone please explain to me how to tell whether substitution (sn1/sn2) or Elimination (E1/E2) im mostly confused on nucleophile or base strong or weak like is there a step by step that you know thats great for knowing what mechanisms to use ? please please be descriptive . write steps to finish mechanism. and explain nucleophile/base/strong/weak and what goes with what mech.
I am having trouble differing between Sn1, Sn2, E1, and E2
reactions. Please help me understand how to approach these
problems. I've attempted to answer them, but I am not confident in
my answers. Please show me how to get to the correct answer.

21. Propose a mechanism to explain this reaction (SN1, SN2, E1 or E2). What is the structure of the product? H- = 22. How can we get this product? CI. CI 11. Predict the result of reacting HBr ROOR HBr
Match the following statements with reaction mechanism
SN1, SN2, E1, or E2. A statement may be true
for one or more mechanisms.
a. The mechanism involves carbocation intermediates. b. The mechanism has two steps. c. The reaction rate increases with better leaving groups. d. The reaction rate increases when the solvent is changed from CH3OH to (CH3)2SO e. The reaction rate depends on the concentration of only the alkyl halide. f. The mechanism is concerted. g. The reaction of CH3CH2Br...
please explain why and how they are E2/SN2/SN1/E1
3. Draw a structural formula for the major organic product(s) of each reaction and specify the mechanism by which each product is formed (SNI, S2, El, or E2). • NaOH H20 CH,CH ON CH,CH OH CH ON CH,OH CH OH Na DMSO
1.(1 pt. each) Consider the following statements regarding Syl, SN2, E1 and E2 reactions. To which mechansims, if any, does each statement apply? If the statement can be applied to more than one mechanism, indicate each mechanism. SNI a) Involves a carbocation intermediate SNIEL b) Substitution at a stereocenter give predominantly a racemic product c) Rearrangements of the carbon skeleton are possible. EL SM d) Is greatly accelerated in protic solvents of increasing polarity SN e) Is first order in...
