Minimum electrophilicity principle in Lewis acid–base complexes of
... Lewis bases (weak and strong), which can form stable compounds with these acids, are considered here. It is expected that more stable complexes are formed by stronger acids. Therefore, according to the MHP and MEP, for each set of complexes which are formed for a given base and different acids, the ...

... The process of recrystallization is used to purify a solid compound. The theory behind it reasons that as crystal X begins growing in solution, molecules of X will fit the crystal lattice better than molecules of Y, and X will be added preferentially. Thus, crystals of pure X will form, and excess Y ...
