Draw the structures of the following :
(i) `XeF_(4)`
(ii) `HClO_(4)`

Explanation

To draw the structures of the compounds XeF₄ and HClO₄, we will follow these steps:

### Structure of XeF₄ (Xenon Tetrafluoride)

1. **Determine the central atom**: In XeF₄, xenon (Xe) is the central atom because it is less electronegative than fluorine (F).

2. **Count the valence electrons**:
- Xenon has 8 valence electrons.
