- what would a detailed step-by-step mechanism be for a reaction between bromine and trans-stilbene if the solvent, ethanol, is a stronger nucleophile than the bromide ions?Explain how these Grignard reagents would react with molecules of their own kind to “self-destruct.”Explain the features of E1 reactions are worthy of note ?
- 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…In this study, the researcher compared S N 2 and E2reaction rates for four substrates.
