Concetrated acedic acid is a Class II combustible liquid. What is the molecular weight of acetic acid that will form 2 moles of CO2 assuming complete combustion.
Sketch Flow diagram and explain the extraction process - What is the purpose of extracting the organic layer with water in the first extraction step?
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
An experiment requires 46.0 of ethylene glycol, a liquid whose density is 1.114 . Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
