Establish the structure of a hydrocarbon `C_5 H_(10) ` from the following facts :
(i) The hydrocarbon yields 2-methyl butane on catalytic reduction.
(ii) The hydrocarbon adds HBr to form a compound (B) which on reaction with moist silver oxide produces an alcohol (C).
(iii) The alcohol (C) on oxidation gives a ketone containing the same number of carbon atoms.

Explanation

To establish the structure of the hydrocarbon \( C_5H_{10} \) based on the given facts, we can break down the problem step by step:

### Step 1: Analyze the first fact
The hydrocarbon yields 2-methylbutane upon catalytic reduction. This indicates that the hydrocarbon must contain a double bond, as catalytic reduction typically involves the addition of hydrogen to a double bond, resulting in a saturated compound.

**Hint:** Catalytic reduction of an alkene leads to an alkane, suggesting the presence of a double bond in the original hydrocarbon.
