- Trimethylphosphine is a stronger nucleophile than triphenylphosphine, but it is rarely usedto make ylides. Why is trimethylphosphine unsuitable for making most phosphorus ylides?How does increasing base, solvent, or alkyl halide or aptly halide + base affect or decreasing them affect the reaction rate for e2/e1 and sn2/sn1? Please provide examplesMake an experimental step-by-step procedure with regards to the synthesis of Butyl Acetate shown below. Please make it detailed and tell the equipment used in the process. Thank you!
- Using resonance structures of the intermediates, explain why bromination of biphenyl occurs at ortho and para positions rather than at meta.Rank the attached alkyl halides in order of increasing reactivity in E2elimination. Then do the same for E1 eliminationWhat is the best way to remeber the differences between Sn1, Sn2, E1 and E2 reations?
- The following compound readily eliminates CO; to form a conjugated six membered ring. (a) Complete the reaction with drawing the possible structure and (b) explain why this reaction goes steadily.if NaNO3 and NH4Cl was dissolved in water separtedly, which one would be the best candidate for cold-pack as a strong reaction? which compound would dissolve faster?For butenafine, develop a synthesis that starts with napthalene and benzene. (aromatic methyl groups can be converted to alkyl bromides using Br2/light, and aldehydes by heating the alkyl bromide in DMSO, eg. ArCH3 to ArCH2Br then to ArCHO).
