Alcohols, Phenols & Ethers · Hydroboration oxidation conversion

The correct sequence of reagents for the above conversion of X to Y is :
  1. (1)(i) NaOH (aq) (ii) Jones reagent (iii) HX3OX+\ce{H3O+}
  2. (2)(i) BX2HX6\ce{B2H6}/HX2OX2\ce{H2O2} (ii) NaOEt (iii) Jones reagent
  3. (3)(i) Jones reagent (ii) NaOEt (iii) Hot KMnOX4\ce{KMnO4}/KOH
  4. (4)(i) NaOEt (ii) BX2HX6\ce{B2H6}/HX2OX2\ce{H2O2} (iii) Jones reagent
We corrected a printing error in the original paper

Option (2): source printed “BX2HX6\ce{B2H6}/HX2OX2\ce{H2O2} (ii) NaOEt (iii) Jones reagent” without the step label “(i)”.
