An aromatic compound (X) contained 58.5% of C, 4.1% of H and 11.4% of N. (X) may be obtained by the action of `HNO_(3)` on a compound (Y).(X) , on reduction, gives a monoacid organic base (Z). Give structural formulae of (X), (Y) and (Z).

Explanation

To solve the problem, we need to determine the structural formulas of the compounds (X), (Y), and (Z) based on the given percentages of carbon (C), hydrogen (H), and nitrogen (N).

### Step-by-Step Solution:

**Step 1: Determine the empirical formula of compound (X)**

1. **Convert percentages to grams**: Assume we have 100 g of the compound.
- C: 58.5 g
