The following thermochemical equation is for the reaction of bromine trifluoride(g) to form bromine(g) and fluorine(g). 2BrF3(g) Br2(g) + 3F2(g) H = 542 kJ How many grams of BrF3(g) would be made to react if 56.6 kJ of energy were provided?

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.
