In the Cannizzaro reaction of benzaldehyde ( aka solventless disproportionation of benzaldehyde in the presences of a strong base such as KOH), what is the internal reduction product?
In a Cannizzaro reaction (unknwon benzaldehyde with 4ml of 10M KOH and 5ml Methanol) 1. Prepare a flow chart of the procedure you plan to use to separate the two possible products from each other. 2. Calculate the amount of 6 M HCl that is needed to acidify your reaction mixture to pH 2 after the reaction is complete. 3. Prepare a flow chart to show how the reaction and isolation process will be conducted and to show the reactions...
What is the purpose of extracting the aqueous layer two more
times with ether in step 5?
What is the purpose of washing the combined organic layers with
NaOH in step 6?
Thank you
Reaction 1: Nitration HNO3 NO2 + H2SO4, H20 NO2 toluene NO2 ortho meta para Procedure for Reaction 1: 1) To a stirred solution of 3 ml (44.7 mmoles) 67 % HNO3 in 3.75 mL of water, H2SO4 (9 mL) was slowly added at 10-15 °C. 2)...
2. Identify the principal organic product of each of the following reactions: (30 pts) (a) acetic anhydride and 2-pentanol (b) 4-methyl-3-penten-2-one and ammonia in water solution (c) acetophenone (methyl phenylketone) and benzaldehyde+KOH in ethanol solvent (d) methyl butanoate and LDA (lithium diisopropylamide) in THF solution, then ethyl iodide (e) butylamine and excess 1-iodobutane (1) acetanilide and LiAlH, in diethyl ether, followed by addition of water.
The density of dichloromethane, an organic solvent, is 1.325 g/cm. If you mix 50 mL water and 50 mL dichloromethane together in a separatory funnel, which layer would be on top? The density of diethyl ether, an organic solvent, is 0.706 g/cm. If you mix 50 mL water and 50 mL diethyl ether together in a separatory funnel, which layer would be on top?
Answer the following before coming to lab: 1.) Based on what you saw last week, which enantiomer of tartaric acid would you expect to co- crystallize with (SS)-1,2-diammoniumcyclohexane? 2.) If you had a neutral aqueous solution of triethylamine, would you add acid or base in order to extract it with an organic solvent? 3.) Now, consider a dichloromethane solution of triethylamine. Would you extract with acidic aqueous or basic aqueous solution in order to get the triethylamine out of the...

1. What experimental difficulty would you encounter if you had neglected to include a drying step before evaporating the ether solution of the neutral organic compound? 1b. An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-mL portions of diethyl ether. A student removes the lower layer after the first extraction and adds the second 10-mL portion of ether to the upper layer remaining in the separatory funnel. After shaking the funnel, the...
