Which of the following is not planar?
Correct answer: D. Propane
- A. Benzene
- B. Formaldehyde
- C. BF3
- D. Propane
Explanation
Propane is not planar because it is a tetrahedral molecule. The four C-H bonds are arranged in a tetrahedral configuration, and the electronegativity of carbon and hydrogen are different. This means that the partial charges on the carbon and hydrogen atoms are not equal in magnitude and opposite in direction, so they do not cancel each other out.

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.
