**Transformation Task:**

Devise routes for the transformation of bromocyclopentane to cyclopentanol and then to cyclopentene using the provided reagents.

**Reaction Scheme:**

- Starting compound: Cyclopentane with a bromine substituent (Br)
- Intermediate: Cyclopentanol (OH)
- Final product: Cyclopentene

**Reagents Available:**

a. NBS, heat  
b. H₃PO₄, heat  
c. H₂O / H₂SO₄  
d. PCC  
e. NaNH₂ / NH₃  
f. H₂CrO₄  
g. HIO₄  
h. H₂ / Lindlar catalyst  
i. H₂O  
j. CH₃OH  
k. OsO₄ / H₂O₂  
l. 1. BH₃  2. H₂O₂, NaOH, H₂O  

**Instructions:**

Specify the reagents you would use to carry out the conversion using the letters from the table. If there are multiple routes to the same product, show only one.

**Reaction Steps:**

- **Step 1:** Convert bromocyclopentane to cyclopentanol.
- **Step 2:** Convert cyclopentanol to cyclopentene.

**Enter the reagents (in order of use):**

- **Step 1:** 
- **Step 2:** 

This exercise involves understanding the mechanisms required to achieve each transformation and selecting the correct reagents.
