When producing a soluble salt in a reaction between an acid and an alkali, how can you prepare dry solid crystals from the solutions 1)evaporation/crystallization
2)filtration
3)condensation
4)nuetralisation

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.
