**Chemical Reaction Reagents and Transformations**

**Instructions:**
Select from the available reagents the one you would use to carry out each of the transformations below.

**Reagents Available:**
- a. KOH
- b. KMnO₄, H₃O⁺
- c. H₂, Pd
- d. CH₂I₂, Zn(Cu)
- e. Hg(OAc)₂, H₂O; then NaBH₄
- f. OsO₄; then NaHSO₃
- g. BH₃; then H₂O₂, ⁻OH
- h. CHCl₃, KOH
- i. O₃; then Zn, H₃O⁺
- j. H₂SO₄
- k. Cl₂
- l. Cl, CO₃H, then H₃O⁺

**Transformations and Reagents Selection:**

1. **Transformation 1:**
   - **From:** Cyclopentene
   - **To:** Cis-1,2-cyclopentanediol
   - **Reagent to Use:** f. OsO₄; then NaHSO₃
   - **Explanation:** Osmium tetroxide (OsO₄) followed by sodium bisulfite (NaHSO₃) is commonly used for dihydroxylation, converting an alkene to a vicinal diol with syn-stereochemistry.

2. **Transformation 2:**
   - **From:** 1-Methylcyclopentene
   - **To:** 2-Methylcyclopentanol
   - **Reagent to Use:** g. BH₃; then H₂O₂, ⁻OH
   - **Explanation:** Hydroboration-oxidation (BH₃ followed by H₂O₂ and hydroxide) leads to anti-Markovnikov hydration of alkenes, forming alcohols at the least substituted carbon of the double bond.
