Who does the first ionizaiton energy of the alkali metal in a given period compare with the first ionization energy of the halogen in the same period. What is the result in terms of how these elements tend to react with each other
Quinine (C20H24N2O2) is the most important alkaloid derived from cinchona bark. It is used as an antimalarial drug.
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.
