Draw the structure of the compound you would expect from SN2
reaction of the molecule below with NaCN.
Use the wedge/hash bond tools to indicate stereochemistry.
Include H atoms at chiral centers only.
If a group is achiral, do not use wedged or hashed bonds on
it.
You may use the OWL references to look up acidities if you want
to compare leaving groups.
