**Question:**
Which compound is likely to have an incomplete octet?

**Options:**
a. NH₃  
b. SO₃  
c. BH₃  
d. CO₂  

**Answer Choices:**
- ○ a
- ○ b
- ○ c
- ○ d

**Explanation:**  
This question asks you to identify which one of the listed compounds is most likely to have an incomplete octet. An incomplete octet occurs when an atom in a molecule has fewer than 8 electrons in its valence shell. In the given options:

- NH₃ (Ammonia) tends to form a complete octet.
- SO₃ (Sulfur trioxide) also completes the octet rule for sulfur.
- BH₃ (Boron trihydride) is notable for having boron, which often forms compounds with incomplete octets.
- CO₂ (Carbon dioxide) forms stable molecules with complete octets.

**Correct Answer:**
c. BH₃

Boron is an example of an element that often forms stable compounds with incomplete octets.
