- 4-bromobenzoic acid (1.0 g) is dissolved in 20 ml dichloromethane. After addition to a separatory funnel, the dichloromethane solution is treated with 20 ml 3.0 M NaOH solution. After the layers are separated, which layer(s) will contain an organic compound (non-solvent)? What would happen if the aqueous layer is treated with 20 ml 3.0 M HCl?7. When you are performing an extraction with diethyl ether and any aqueous solution, the bottom layer in the separatory funnel is the _______ ether (organic) layer aqueous layerWhy would you expect 2-bromoethanol to decompose to a gluey product over time?
- How to go from 3-oxocyclohexane-1-carbaldehyde to 3-hydroxycyclohexane-1-carbaldehyde, using a protection reagent for the aldehyde group.1) Based on the Material Safety Data Sheets (MSDS) for the compounds, which of the compounds in this experiment is the most hazardous, and why (you have been given a representative aryl halide rather than all of the alkenes – as the products are all new, there’s not a simple answer to gauge their potential hazard)? 2,3-dihydrofuran,2-Mercaptobenzimidazole,Selectfluor, Dimethylformamide,dichloromethane-methylene chloride.In this study, the researcher compared S N 2 and E2reaction rates for four substrates. Three of the substrates had a second halogen on the bposition in the molecule. This work also compared the behavior of two nucleophiles:dianion I and II. You should read the abstract and look at Scheme 1 (p. 3082) and Table 4(p. 3086). Abstract: The gas-phase reactions of benzoate and phenolate containing dianions with a series of ‚-substitutedalkyl bromides (X-CH2CH2Br, X ) H, F, Cl, Br) have been studied in a quadrupole ion trap mass spectrometer.Branching ratios between SN 2 and E2 products were measured and rate constants were determined. The‚-halogens increase both the S N 2 and E2 rates, but the effect is greater for the latter process and thereforethese substituents lead to an increase in the amount of elimination. The kinetic data for the SN 2 reactions canbe analyzed via a two-parameter, linear free-energy relationship and the results indicate that field-effects (i.e.,electron-withdrawing…
