Question

Which of the following molecules are linear? (I) C₂H₂ (II) CO₂ (III) NO₂^- (IV) NO₂⁺ (V) H₂O

Quizplus · Accepted Answer

Molecules (I) CO2, (II) COS, and (IV) NO+ are linear due to their molecular geometry. CO2 and NO+ have linear structures because of the double bonds and the absence of lone pairs on the central atom, leading to a 180-degree bond angle. COS is also linear as it resembles the structure of CO2, with sulfur replacing one oxygen, maintaining the linear geometry.
