MDCAT Chemistry QUESTION #4365
Question 1
The theories which explain the formation of sigma ($\sigma$) and pi ($\pi$) bonds are EXCEPT:
  • MOT
  • VBT
  • VSEPR
  • CFT✔️
Correct Answer Explanation
Valence Bond Theory (VBT) explains $\sigma$ and $\pi$ bond formation through orbital overlap. Molecular Orbital Theory (MOT) also describes bonding. VSEPR predicts shape. Crystal Field Theory (CFT) deals with d-orbital splitting in coordination complexes — it does NOT explain $\sigma$ and $\pi$ bond formation.
