The C2H2 molecule is linear which can be deduced from the numbers of σ and π bonds present in the molecule?
Correct answer: C. Option C: C2H2 has three sigma (σ) bonds and two pi (π) bonds.
- A. Option A: C2H2 has two sigma (σ) bonds and two pi (π) bonds.
- B. Option B: C2H2 has two sigma (σ) bonds and one pi (π) bond.
- C. Option C: C2H2 has three sigma (σ) bonds and two pi (π) bonds.
- D. Option D: C2H2 has four sigma (σ) bonds and two pi (π) bonds.
Explanation
C2H2(acetylene) has a triple bond between the two carbon atoms, consisting of one sigma (σ) bond and two pi (π) bonds. Futhermore each carbon atom has a sigma bond with one hydrogen atom.Hence it has total of three sigma (σ) bonds and two pi (π) bonds.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
