- I am working on a practice assignment for my organic II course and am having difficulty with a question that asks to identify the reaction sequence used to synthesize isopropylcyclopentane. I would really appreciate the help!Give detailed answer- Provide example of compound that fulfil each criteria below. Explain why-A)1,2-disconnectionB)1,4-disconnectionC)1,5-disconnectionD)1,6-disconnectioncan i get help drawing out actual structures including the nucleophilic addition of Cy2NH to parafomaldehyde and its hemiaminal intermidiate and the condensation step when it is displaced by terminal alkyne forming allene, also what is dioxane getting rid of as the solvent, thanks
- Describe how the product is purified. 4,4'-DIBROMOBIPHENYL [Biphenyl, 4,4'-dibromo-] Submitted by Robert E. Buckles and Norris G. Wheeler1. Checked by R. S. Schreiber, Wm. Bradley Reid, Jr., and Robert W. Jackson. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°.

- Explain the features of E1 reactions are worthy of note ?i need help with predicting the Ir spec for the final product i also need to make it look like the example with the table and the 1h-nmr digram i made an example of how it needs to look like the lab called Electrophilic Aromatic Substitution: Friedel-CraftsAlkylationIn 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…
