**Question:**

What order of reagents should be used to synthesize the following product from methylcyclopentane?

**Reagents:**

(A) Br₂  
(B) Br₂, hv  
(C) KOH, heat  

**Diagram Explanation:**

- The starting material is methylcyclopentane, depicted as a cyclopentane ring with a methyl group.
- The product is a brominated cyclopentane with two bromine atoms attached, indicated as a racemic mixture with one bromine atom on each side of the ring.

**Options:**

- ○ C, then B, then A
- ○ B, then A, then C
- ○ C, then A, then B
- ● B, then C, then A
- ○ A, then B, then C
- ○ A, then C, then B

**Correct Answer:** 

B, then C, then A 

In this synthesis, initiating with bromination using light (Br₂, hv) introduces bromine radicals, followed by elimination with KOH and heat, and concluding with the addition of Br₂ creates the final dibromide product.
