What is the Lewis structure of CO₂? 2. Which molecule has a central atom with no lone pairs?

1. The Lewis structure of CO₂ shows:

• Carbon dioxide ($\text{CO}_2$) has a central carbon atom double-bonded to two oxygen atoms.
• Therefore, it has two double bonds.
• The correct option is B.

$$\boxed{\text{B}}$$

2. Which molecule has a central atom with no lone pairs?

• A) $\text{NH}_3$: Nitrogen has one lone pair.
• B) $\text{H}_2\text{O}$: Oxygen has two lone pairs.
• C) $\text{CH}_4$: Carbon has no lone pairs.
• D) $\text{SO}_2$: Sulfur has one lone pair.
• The correct option is
