Identifying Reactions Using IR Spectroscopy
When 2-bromopropane reacts with ethoxide ion, two products are formed; one is the product of Sn2 substitution and the other is the product of E2 elimination. What is the the structures of both products and how can you distinguished them using IR spectroscopy?
