Which one of the followings can form strong sigma bond?
Correct answer: B. sp-sp
- A. sp3 sp3
- B. sp-sp
- C. sp3 sp2
- D. All have same strength
Explanation
This type of hybridization involves two atoms, each with an sp hybridized orbital, forming a sigma bond. In sp hybridization, one s orbital and one p orbital mix to form two sp hybrid orbitals. These orbitals are linearly arranged. An example of sp-sp hybridization can be observed in the formation of a sigma bond between two carbon atoms in acetylene (C2H2).

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.
