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,...

Hello, I need help understanding a lab we are doing in class tomorrow. I need to know which is the "ORGANIC LAYER" ... we are using a separatory funnel, and I would like to know whether the organic layer will be on top or on the bottom. This is in order for me to correctly carry out the experiment. The lab is similar to this one I found online, and its very vague for me as to what is the...

Use retrosynthetic analysis to design a synthesis on paper for the transformation of 2-chloro-3-methylbutane into 3-methylbutanal as shown below. You'll need six of the following reagents. Order the correct ones in order 1-6.The one you don't use will be number 7 through 10. But order the 7+ ones in analagous order to the synthesis. For instance, if your first step is a zaistev elimination, and you have a bulky base and a nonbulky base, then reagent number 7 should be the bulky base. If your...
