What physical property of the triethylene glycol solvent facilitates the rate of the reaction? Explain.
Organic Chemistry Post Lab Questions for the Synthesis of Luminol synthesis of Luminol from 3-nitrophthalic acid and hydrazide 1. A. Draw a well-labeled diagram which shows the singlet state, singlet excited state and the triplet state in a energy level diagram. Show the spin of electrons in each of these states. B. Show transitions in your diagram and label the radiative processes as either phosphorescence or fluorescence C. Discuss which of these are "allowed "transitions and which are "forbidden" transitions....
What is the newman projection for triethylene glycol?
Explain the difference in physical properties of the polyesters- nylon, phthalic anhydride + ethylen glycol, and phthalic anhydride + glycerol?
3) Critical analysis (3 points) (a) Why did you have to heat this reaction to such an extreme temperature? Use the mechanism you drew as a hint (b) Which is the slow step - the first, or second? In this experiment, you will react the product you made in last week's experiment (meso-stilbene dibromide) with strong base in an elimination experiment. This reaction with yield an alkyne, diphenylacetylene. The strong base you will use is potassium hydroxide. The second step...
After performing dehydrobromination of meso-stilbene dibromide, why did we have to heat the reaction to such an extreme temperature? And what is the slow step in this reaction - first or second? Why? OH КОН vorovo Br 190 °C Triethylene glycol solvent Diphenylacetylene meso-stilbene dibromide Figure 1. Reaction Scheme.
7) Which solvent will lead to the greatest rate of SN2 reaction? Explain a. H2O b. CH3OH c. (CH)SO d. both a. and b. will give the greatest rate of SN2 reaction e. solvent has no effect on the rate of SN2 reaction
sand doesnt burn. is this a chemical or physical property or reaction?
Explain the effect of the solvent on the reaction kinetics with respect to an SN1 mechanism? - solvent used was 60/40 acetone/water solution up to 100ml
Explain the following statements. MeOH is NOT a good solvent for S_N2 reaction. Hexane is NOT a good solvent for S_N1/S_N2 reaction. Acetone is a good solvent for S_N2 reaction. Iodide is a better leaving group than chloride. Tosylate is a better leaving group than iodide. (CH_3)_3CO^- is a stronger base than CH_3CH_2O. CH_3CH_2NH_2 is a stronger nucleophile than CH_3CH_2OH.
What physical property of the FD&C dyes is the basis of the resolutions you will perform in this experiment? Briefly explain.
