 (E)‐3‐chloropropenoic
 acid
 and
 the
 (Z)‐3‐chloropropenoic
 acid.
 
 The
 E
 isomer
 will
 contain
 higher
 J
 values
 because
 their
 distances
 are
 larger,
 and
 the
 Z
 isomer
 will
 contain
lower
J
values
because
their
internuclear
distances
are
smaller.


The
Reason
 for
the
two
doublets
is
because
Ha
 couples
with
Hb
to
give
a
doublet
and
Hb
 couples
 to
Ha
to
make
another
doublet.
