Organic chemistry post-lab question: "Why is important
to add the alkyl halide dropwise in your reaction? (Hint: your
reaction is not heated, but you still need a water-cooled
condenser!)" Please answer in detail!

The Grignard reaction is an important synthetic process by which a carbon-carbon bond is formed. Magnesium metal is first reacted with an organic halide. The resultant organo-magnesium halide (Grignard reagent) is then combined with a carbonyl compound, ultimately...

Consider the balanced redox reaction taking place in an acidic aqueous solution vo," (aq) +SO,'(aq) Vo(aq) +0,- (aq) The unbalanced oxidative half-reaction for this redox reaction is: VO, (aq) → VO" (ag) Because the reaction takes place in aqueous solution, the reaction can be balanced by adding water. 2. Add water to reaction (la) to balance the oxygen. This will give reaction (1b). (1b) Because the reaction takes place in...

what is the pH of .10 M solution of HCL
Name - TA - Laboratory Date - Section Experiment 10-Post-lab Questions 1. What is the pH of a 0.10 M solution of HCI? 2. If 50 mL of 0.10 M HCl is diluted to a total volume of 100 mL by adding distilled water, what is the HCl concentration in the new solution? 3. How many moles of NaOH are required to neutralize all of the HCl in the 100...

4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...

Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...

Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...
