The hybridization of carbon in diamond, graphite and acetylene is respectively:
Correct answer: C. sp3, sp2, sp
- A. sp3, sp, sp2
- B. sp, sp2, sp3
- C. sp3, sp2, sp
- D. sp2, sp3, sp
Explanation
The hybridisation of carbon atom in diamond, graphite and acetylene are respectively sp3, sp2, sp. In diamond, each carbon combine with 4 other carbon atoms with four sigma bonds. Hence, the hybridization of carbon is sp3. In graphite, each carbon combines with 3 other carbon atoms with three sigma bonds. so sp2 hybridization. In acetylene, one carbon combines with another carbon atom with three bonds (1 sigma and 2 pi bonds). so sp2 hybridization.

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.
