20. In the formation of the following ether, which reaction is preferred and why? (A) Reaction B is preferred because the oxidation step works best for primary alcohols. (B) Reaction A is preferred over reaction B because the smaller methyl iodide would make a better nucleophilic target. (C) Reaction A is preferred because the the formation of the carbocation would be stabilized in the benzylic position. (D) Reaction B would be preferred because Iodine is a better leaving group for the SN1 reaction. (E) There is no difference in these two reactions they would give approximately the same yields.
