Why can water not be used during the reaction? Cl Cl DMF (cat.) DCM, reflux
What do you expect the temperature of the reaction to be during reflux? Why?
can you give the product for each of these reaction? CH 3 KCN DMF Cl Br NaH acetone Ho CH3 NaH Br acetone HO 0 NaOH CH3CN KCN CH CN снз-CH2-CH2-8-11-CH3 0 3 (solvent) SO CH
in 1) this reaction, professor explain that Cl ion can react if there is little water. So ..... Why does 'Cl react or water react' differ depending on the amount? Could you explain it in detail and clearly please? +plus question 2) why epoxide ring can be opened by nucleophile? 3) why electrons which exist other phase cannot react? H OH H H Cl2 NaOH NaCl H20 H2о H20 H H H CI Cyclohexene trans-2-Chloro- 1,2-Epoxycyclohexane (73%) cyclohexanol 02016 Cengage...

Why would it be problematic to perform an acid catalyzed epoxide ring opening reaction under reflux conditions? Be specific. Provide the potential side product(s) that would result from carrying out the following reactions under reflux conditions. Hint
3. Why should reflux of the microscale reaction mixture be gentle, with the con- densation ring remaining close to the surface of the liquid in the test tube?
Can someone show the mechanism for all the steps in the reaction below. CH CH reflux 2 PhMgBr ether cold reflux 에11 e11 1% CHP CH3 CH2 Ph 대1
In a reflux apparatus, why is it important for joints between glassware to be keck clipped and properly greased? A. To ensure that water does not leak from the condenser. B. It does not matter, as we are not collecting the vapor. C. None of these answer choices are correct. D. To ensure a tight seal to prevent the loss of solvent over the course of the reaction.
