Web5. Identify the aqueous layer in the flask based on the density of the solvents. 6. Remove the stopper. Slowly open the stopcock and collect the lower layer in a 125 ml Erlenmeyer flask. Collect the top layer in another flask. (First part of separation, with dichloromethane and 5% HCl, top layer is aqueous layer Acid-Base Extraction 1. Web4-bromobenzoic acid (1.0 g) is dissolved in 20 ml dichloromethane. After addition to a separatory funnel, the dichloromethane solution is treated with 20 ml 3.0 M NaOH solution. After the layers are separated, which layer(s) will contain an organic compound (non-solvent)? What would happen if the aqueous layer is treated with 20 ml 3.0 M HCl?

WebThe facts. When a mixture of methane and chlorine is exposed to ultraviolet light - typically sunlight - a substitution reaction occurs and the organic product is chloromethane. CH 4 + Cl 2 CH 3 Cl + HCl. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.
