What is the theoretical yield of tert-butyl chloride in this experiment? Synthesis of tert-butyl chloride: 25.5 mL of cold HCl and 15.7 mL of t-butyl alcohol in a separatory funnel then the aqueous layer is drained. Then washed with 15 mL of water and aqueous layer is drained again. Then washed with 15 mL of 5% sodium bicarbonate then drain aqueous layer. Lastly, 15 mL of water and drain aqueous layer. Perform distillation and dry out with anhydrous sodium sulfate....
SYNTHESIS OF T-PENTYL CHLORIDE LAB Provide a stoichiometry table for the reaction being performed in this lab. PROCEDURE Preparation oft-Pentyl Chloride In a 125-mL separatory funnel, place 10.0 mL of tert-pentyl alcohol (2-methyl-2- butanol, MW = 88.2, d = 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separa- tory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully...
MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...
The alcohol could easily be converted to a tosylate, a good leaving group, and a conventional substitution reaction could have been performed instead of the nucleophilic aromatic substitution (NAS) reaction. Why was the NAS reaction the preferred method? (Hint : Look up the nucleophiles of both reactions on chemical manufacturing site.) Part A: Synthesis of (t)-N,N-dimethyl-3-phenyl-3-(4- trifluoromethylphenoxy)propanamine 1. To the 250-mL round-bottom flask (RBF) containing (t)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-...
how do i calculate the number of moles, theoretical yield, and limiting reagent on the READ ABOUT part? thank you i need help on READ ABOUT: Calculate the number of moles of 2-methyl-2-butanol and hydrochloric acid (concentrated HCl is 12 M). Based on the balanced equation, determine the limiting reagent and the theoretical yield of 2-chloride-2-methylbutane. PREPARATION AND ANALYSIS OF T-AMYL CHLORIDE ОН HCI (conc.) + H2O DISCUSSION: Compounds with good leaving groups often participate in substitution reactions. Two limiting...

Propose another way of synthesizing NMP from the amino ketone hydrochloride salt starting material you used. Part A: Synthesis of (t)-N,N-dimethyl-3-phenyl-3-(4- trifluoromethylphenoxy)propanamine 1. To the 250-mL round-bottom flask (RBF) containing (t)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4- chlorobenzotrifluoride and 30 mL of dimethylacetamide (DMA) 2. With stirring, add to this mixture 30 mL of 1.0 M potassium tert-butoxide (caustic alkali!) in tert-butyl alcohol using a syringe 3. Using a simple distillation apparatus,...
How can the NMP oxalate salt be converted back to NMP? Here is the procedure: PROCEDURES Part A: Synthesis of (±)-N,N-dimethyl-3-phenyl-3-(4-trifluoromethylphenoxy)propanamine To the 250-mL round-bottom flask (RBF) containing (±)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-chlorobenzotrifluoride and 30 mL of dimethylacetamide (DMA).

Just Answer Question 5 Synthesis of 2-chloro-2-methylbutane (literature version) Concentrated aqueous hydrochloric acid (HCI, 3.3 equivalents) was slowly added to 2-methyl-2-butanol (1.0 equivalents) in a 100 mL round bottom flask with stirring. The reaction was stirred for 15 minutes at room temperature. Upon completion, the reaction mixture was transferred to a 60 mL separatory funnel and the aqueous layer was removed. The organic layer (i.e. the product) was successively washed with: (1) saturated aqueous NaCl (brine), (2) saturated aqueous NaHCO,...
