You dissolve the sample of fd& c red 40 (molar mass 496.4200 g/mol) in enough water to make 250.0 ml of solution. we call this the stock solution. what is the concentration of the stock solution in terms of molarity?

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i. e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
