Answer: CO2.
- A CO2
- B H2O
- C NH3
- D CH4
Correct answer: A. CO2
Explanation: CO2 has two double bonds and no lone pairs on carbon, giving a linear geometry.
VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.
Concept context
Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
