Treatment of cis-2-bromocyclohexanol with NaOH yields cyclohexanone instead of an epoxide. Draw curved arrows to show the movement of electrons in this step of the reaction mechanism.

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →
