The electronic structure of carbon monoxide is represented as:
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
CO forms a coordinate bond. Carbon has 4 valence electrons and oxygen has 6. Carbon and oxygen form a double bond by sharing two bond pairs, in which both contribute to 2 electrons to form a double bond. Now, oxygen's octet is complete but carbon is still left with 2 valence electrons and has a total of 6. So to attain stability oxygen contributes one of its lone pair of electrons to the carbon atom in the formation of a coordinate bond.

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.
