I am having trouble with this reaction: 1-Hexene (C6H12) is combined with Dichloromethane (CH2Cl2) and silica gel (SiO2) to create compound A. Compound A then has Phosphorus tribromide (PBr3) to get compound B. Then Sodium bicarbonate (NaHCO) is funneled into compound B to get compound C. Sodium chloride (NaCl) is added to compound C to get compound D. Compound D finally has Sodium sulfate (Na2SO4) added to it to get the final compound E. The example given does not let me know what kind of reactions are taking place. All I know is that it is a Markovnikov's reaction for the first three, but I'm unclear if it is that reaction for all of the compounds later added. Thank you in advance!
