1. a) The Williamson synthesis is a very important method to prepare asymmetric ethers. In the first step of this reaction the alcohol is converted to an alkoxide as shown. Why is this necessary? ROH+ NaHRONa+ + H₂ b) The Williamson synthesis works best if the alkyl halide is primary. Why is this true? c) Why is NaH rather than NaOH used in this reaction?
