skeletal formulae
skeletal formula
名詞
(chemistry)
A
structural
formula
which
is
reduced
(i.e.,
skeletal)
in
the
sense
that
carbon
atoms
forming
the
backbone
of
the
structure
(esp.
of
an
organic
compound)
are
not
labeled
—
they
are
shown
simply
as
vertices
—
and
hydrogen
atoms
are
not
shown
at
all
(except
those
which
are
bonded
to
heteroatoms,
or
the
exceptionally
labeled
carbon
atoms)
but
heteroatoms
are
always
labeled.
(Labels
of
labeled
hydrogen
atoms
are
written
next
to
labels
of
the
atoms
that
they
are
bonded
to,
without
a
bond
drawn
between
them.
If
there
are
several
labeled
hydrogen
atoms
bonded
to
the
same
atom
then
they
are
written
as
an
H
with
a
subscript
for
their
number.)
Carbon
atoms
which
are
(optionally)
labeled
tend
to
be
in
reactive
extremities
of
the
molecule,
not
the
backbone
of
it.
