An alkance (A) `C_(5)H_(12)` on chlorination at `300^(@)C` gives a mixtrue of four different monochlorinated derivatives `(B), (C ), (D)`, and `(E )`. Two of these derivatives give the same stable alkene `(F)` on dehydrohalogenation. On oxidation with hot alkaline `KMnO_(4)` followed by acidification, `(F)` gives two products `(G) and (H)`. Give the structrues of `(A) t o (H)` with proper reasoning.

Explanation

To solve the problem step by step, we will identify the structures of the compounds A to H based on the information provided.

### Step 1: Identify the alkane (A)
The alkane with the formula \( C_5H_{12} \) is pentane. The structure of pentane can be represented as follows:

**Structure of A (Pentane):**
\[
\text{A: } CH_3-CH_2-CH_2-CH_2-CH_3
