Identify the atoms in each of the following compounds which do not obey octet rule:
`" "SO_(2),NH_(3),OF_(2),BCl_(3),PCl_(3)`

Explanation

To identify the atoms in the given compounds that do not obey the octet rule, we will analyze each compound one by one, drawing their Lewis structures and counting the valence electrons around the central atom.

### Step-by-Step Solution:

1. **SO₂ (Sulfur Dioxide)**:
- Draw the Lewis structure: Sulfur (S) is the central atom, bonded to two oxygen (O) atoms.
- Sulfur has 6 valence electrons, and each oxygen has 6 valence electrons.
- In the structure, sulfur forms double bonds with both oxygen atoms and has one lone pair of electrons.
