Which molecule has a linear shape?
Answer and explanation
Correct answer: A.
- Step 1: In carbon dioxide (), the central carbon atom forms two double bonds with oxygen atoms () and has zero lone pairs.
- Step 2: With a steric number of , the carbon atom undergoes hybridization, directing the two double bonds apart to minimize electrostatic repulsion.
- Step 3: As a result of this bond angle, the molecular geometry of carbon dioxide is linear.
