The total number of bond angles in methane is:
Correct answer: D. 4
- A. 2
- B. 3
- C. 5
- D. 4
Explanation
Methane is a tetrahedral molecule with a central carbon atom bonded to four hydrogen atoms. Each hydrogen atom is bonded to the carbon atom, resulting in four sigma (σ) bonds and, therefore, four bond angles. The bond angles in methane are approximately 109.5 degrees, and they are all the same, creating a symmetric tetrahedral arrangement.

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.
