What hybridization is present on carbon atoms in ethyne (C₂H₂)?
Correct answer: C. sp
- A. sp3
- B. sp2
- C. sp
- D. dsp2
Explanation
Ethyne (C2H2) has sp hybridization. This means that each carbon atom in ethyne forms two sigma bonds using one s and one p orbital, resulting in a linear molecular geometry. The two carbon atoms are joined by a triple bond composed of one sigma bond and two pi bonds.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
