Correct answer: B. 7 sigma and 3 pi
- A. 5 sigma and 5 pi
- B. 7 sigma and 3 pi
- C. 8 sigma and 2 pi
- D. 6 sigma and 4 pi
Explanation
The number of sigma and pi-bonds in 1-butene 3-yne are 7 sigma and 3 pi. It has one C=C double bond which contains one pi bond. It has one C≡C triple bond which contains two pi bonds. It has 3 carbon carbon sigma bonds and 4 C−H pi 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.
