Step by step
Solved in 2 steps with 2 images
- propose a synthesis for ortho bromobutylbenzene starting with benzene and any other reageants.Avoid producing para isomer1.) Design a detailed synthetic route to prepare the following compound using cyclopentane, cyclohexanone, cyclohexan-1,3-dione, benzene, phenol, diethyl malonate, ethyl acetoacetate, as the starting materials, and any other reagents of less than 5 carbon atoms (including 5 carbon atoms). O OEtWhich of the following statements is FALSE? OA Bromobenzene is less reactive than benzene in an electrophilic aromatic substitution reaction because bromine has a strong electron withdrawing inductive effect. OR In phenol, the OH group strongly donates electron density to the ring via resonance, but it withdraws electron density via the inductive effect. o The nitro group in 1-chloro-4-nitrobenzene is activating to the ring with regard to nucleophilic aromatic substitution. Op In benzoic acid, the -COOH group is a meta director and it activates the ring (makes it more reactive than benzene) for electrophilic aromatic substitution.
- a) Write out the first 3 steps only(to the tetrahedral intermediate shown) in the 6-step arrow pushing mechanism showing how ethyl propanoate is hydrolyzed in acid to form propanoic acidand ethanol. b) NaOH/H2O also serveto hydrolyze an ester; briefly explain why NaOH/H2Ois generally preferable.Draw the major organic product you would expect to isolate from the reaction of p-bromoethoxybenzene with a misture of HNO3HNO3 and H2SO4H2SO4.Provide a retrosynthetic analysis and forward synthesis for the compound shown below. H- and any other reagent of one carbon or less.
- Please help with the following ochem synthesis... Provide the stepwise synthesis for PhCOCH(CH2CH2CH3)COCH3 by using either ethyl acetoacetate or malonic ester synthesis. Provide the bond line structures for the major organic products obtained in each step of the proposed synthesis and use the correct arrows to show the flow of electrons.NonePropose a synthesis of the molecule below. You may use benzene, any organic molecule with four or fewer carbons ( with any functional group) and any inorganic reagent you wish.
- Complete the electron‑pushing mechanism for the given ether synthesis from propanol in concentrated sulfuric acid at 140 °C by adding any missing atoms, bonds, charges, nonbonding electron pairs, and curved arrows. Draw hydrogens bonded to oxygen, where applicable.6) Provide the structure of the major organic product in the reaction shown below. NaBH4 CH3 HOCH3The question is: "Draw the curved arrow mechanism for the reaction between pentan-2-one and (CH3)3O– in t-butanol to form an enolate. Draw all electrons and charges on both resonance structures. Then answer the question about the reaction." I got the initial arrows correct, but am not entirely sure what the carbanion intermediate would look like and then what the curved arrows would be to convert it to its final oxanion form
