basicity
For
Brønsted bases
, the tendency of a compound to act as
hydron
(
proton
) acceptor. The basicity of a
chemical species
is normally expressed by the
acidity
of the conjugate acid (see
conjugate acid–base pair
). For Lewis bases it relates to the
association
constants of
Lewis adducts
and
π-adducts
.
