Say the type of reaction (SN1, SN2, E1 or E2) and detail the mechanism:
4-bromo-2-ethyl-2-pentene + methanol
Step by step
Solved in 2 steps with 2 images

Write out an equation for the reaction Assign each the appropriate symbol for the mechanism of the reaction (E1 or E2) Draw a suitable mechanism for the reactionSay the type of reaction (SN1, SN2, E1 or E2) and detail the mechanism: 1-chloro-1,2-dimethylcyclohaxane + sodium methoxide in methanol.Give an example of how 2-chloropentane can participate in an E2 reaction by showing the reaction mechanism.
- Two substitution products result from the reaction between 3-chloro-3-methyl-1- butene with sodium acetate (CH3COO – Na +) in acetic acid under SN1. Identify the products.Predict the product formed in the nucleophilic aromatic substitution reaction between 1-chloro-2,4-dinitrobenzene and sodium methoxide (NaOCH3). Draw the mechanism for the reaction, showing why the product you have selected is formed.Bicyclo-2,5-heptadiene can be prepared in two steps from cyclopentadiene and vinyl chloride. Provide a mechanism for each step.

Write an equation for the reaction Propose a mechanism to account for the formation of butylbenzene Propose a mechanism to account for the formation of (1-methylpropyl)benzeneProvide the mechanism for the following reaction (1) PhMgBr (2 equiv) (2) H3O+ workup OH2-bromo-2-methylbutane with sodium methoxide under SN2/E2 conditions substitution product elimination product both substitution and elimination products no products
- Compound A reacts with the reagents shown in the image. Write the mechanism, step by step, for the formation of product B. Note that B has the molecular formula C14 H18 O.The reaction of (S)-2-bromopentane with potassium cyanide to yield 2-methylpentanenitrile (2-cyanopentane) occurs due to a nucleophilic substitution pathway. The reaction is 100% stereospecific. Please explain what this observation tells about the mechanism of the reaction.3-Chloro-1-butene reacts with sodium ethoxide in ethanol to produce 3-ethoxy-1- butene. The reaction is second order, first order in 3-chloro-1-butene, and first order in sodium ethoxide. In the absence of sodium ethoxide, 3-chloro-1-butene reacts with ethanol to produce both 3-ethoxy-1-butene and 1-ethoxy-2-butene. Explain these results.
