Draw the skeletal structure of the major organic product resulting from the following synthesis steps.
(a) Benzyl bromide is reacted with solid Mg in diethyl ether. (Draw organometallic compounds using single bonds to and from the ligand.)
(b) The product from (a) is reacted with ethylene oxide followed by acid workup.
(c) The product from (b) is reacted with PCC in methylene chloride (a.k.a. dichloromethane or DCM).
(d) The product from (b) is instead reacted with chromic acid.
