Question

Which of the following molecule does not have a linear arrangement of atoms?

Options

• H₂S

• C₂H₂

• BeH₂

• CO₂

Answer 1

H₂S

Explanation:

The hybridization should be sp (linear shape, 180° angle) for atoms in a linear arrangement. Only H₂S has sp³-hybridization and thus has an angular shape, whereas C₂H₂, BeH₂, and CO₂ all have sp-hybridization and thus have linear atom arrangements.
