The reaction of 3-chloro-1-butene with ethoxide ion in ethanol yields only 3-ethoxy-1-butene; the rate of this reaction depends on the concentration of both 3-chloro-1-butene and ethoxide ion. The reaction of 3-chloro-1- butene with ethanol alone, on the other hand, yields both 3-ethoxy-1-butene and 1-ethoxy-2-butene. How do you account for these different results?

How to do a summary on this compound:
1)mention how many signals there are in the NMR and what this
means.
2) Find the location of the signals and describe what they
mean.(ex peak 1.3 could indicate a possible CH>CH2>CH3)
3)Talk about the integrals and the possible number of hydrogen's
there could be based on the other integrals.
4)Discuss the signal splitting and how many neighbors each
proton has.
