Select all possible structures with a molecular ion at 55, an absorption in its ir spectrum at ~2250 cm-1 and no absorption in its ir spectrum above 3000 cm-1. assume each compound has an sp3 hybridized c-h absorption in its ir spectrum.

If 200.0g of copper(ll) sulfate react with an excess of zinc metal, what is the theoretical yield of copper

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.
