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
tetrahedral stereo mode
(specific means unspecified query matches specified target)
consider double bond stereochemistry
consider stereochemistry of odd-numbered cumulenes
(requires global stereo matching model)
consider axial stereochemistry
(requires global stereo matching model)
consider syn/anti stereochemistry
stereo matching model
charge matching
radical matching
isotope matching
valence matching
bond vagueness
list all matches' atom index arrays
