Consider the following reaction
NaOEt
------>
EtOH
a) Identify the mechanism(s) by which the reaction will occur. If there is more than one mechanism that can operate, identify the mechanism that will predominate. Explain your reasoning clearly.
b) Predict all possible product(s) that will be formed and identify them as major and minor products.
Homework Answers
