Draw Lewis structures for the following molecules and identify the atoms in each of the following which do not obey octet rule :
`H_(2)S" "SF_(2)" "BF_(3)" "SO_(2)" "PCl_(3)`

Explanation

To solve the problem of drawing Lewis structures for the given molecules and identifying which atoms do not obey the octet rule, we will follow these steps for each molecule:

### Step 1: H₂S (Hydrogen Sulfide)

1. **Count the valence electrons**:
- Sulfur (S) has 6 valence electrons (group 16).
- Each Hydrogen (H) has 1 valence electron, and there are 2 H atoms: 2 x 1 = 2.
- Total = 6 + 2 = 8 valence electrons.
