Which of the following molecules contain sp hybridized carbon atoms?

Question

Quizplus · Accepted Answer

The molecules with sp hybridized carbon atoms have a linear geometry. In molecule A, the carbon atoms in both triple bonds with nitrogen are sp hybridized and have a linear geometry. In molecule B, the carbon atoms in both double bonds with oxygen are sp hybridized and have a linear geometry. Therefore, both A and B contain sp hybridized carbon atoms, making choice C the correct answer. Molecule C does not have a linear geometry, so it does not contain any sp hybridized carbon atoms.
