In its ground state, the number of unpaired electrons in carbon are:
Correct answer: C. 2
- A. 1
- B. 3
- C. 2
- D. 4
Explanation
The ground state electron configuration of carbon is 1s² 2s² 2p². According to Hund's rule, the two electrons in the 2p subshell will occupy separate orbitals with parallel spins (2pₓ¹ 2py¹). This results in 2 unpaired electrons.

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.
