Compound
I
has
a
conjugated
double
bond
that
allows
for
more
single
bond
character
to
the
carbonyl
group.
This
results
in
absorption
of
the
carbonyl
group
at
a
lower
wavenumber .
for
compound
II
the
oxygen
atom
allows
for
additional
resonance
structures,
which
results
in
more
single
bond
character
for
the
carbonyl
group.
This
