JChem® Structure Comparator

Please draw two structures and compare them with JChem®. Draw explicit H atoms on an atom in the query (author's structure) to exclude substitution at that site in the target (response).
 
Draw the target (student's response): Draw the query (author's reference structure):


type of match
set StereoSearch to true
(false: all stereochemistry is ignored)
set ExactStereoMatching to true
(false: query nonstereo matches target stereo)
set DoubleBondStereoMatching to none
(none: E matches to Z)
set stereo matching model to local
charge matching
radical matching
isotope matching
valence matching
list all matches' atom index arrays
