Pyridine A/-oxide exhibits a dipole moment of 4.25 D (cf. pyridine, 2.2 D) and it is
important to note, however, that because of the formal positive charge upon the
nitrogen atom, pyridine A/-oxides are also susceptible to nucleophilic reactions at
...
Pyridine and its simple derivatives are stable and relatively unreactive liquids,
with strong penetrating odours that are unpleasant to some people. They are
much used as solvents and bases, especially pyridine itself, in reactions such as
N- ...
