Provide a structure for the expected product of the following reaction. The figure shows a scheme of a reaction. The reactant has the following structure: a six-carbon ring with alternating double and single bonds, with a CH2Br attached to the first carbon. At the first step, the reactant is treated with Mg labeled with 0 above the atom. At the second step, the reactant is treated with a compound with the following structure: a three-membered ring. The first atom has a CH3 group attached with a dash below and a CH2CH3 group attached with a wedge above the plane of the ring. The second (clockwise) atom of the ring is an O atom, the rest are C atoms. At the third step, the reactant is treated with H3O plus.

1) mg 2) 3) H3O+
