Draw structural formulas for the alkoxide ion and the alkyl(aryl)bromide that may be used in a Williamson synthesis of the ether shown. ch3-0-chch3 with a ch3 off of the second carbon from the right Draw both structures in the single sketchpad. Draw the structures only; do not include a + sign. Do not include a metal cation, for example Na+, with the alkoxide structure.
