When 's' character of hybridized orbitals decreases the bond angle:

Correct answer: A. Decreases.

  • A. Decreases.
  • B. Increases.
  • C. Becomes zero.
  • D. Does not change.

Explanation

The correct answer is that the bond angle decreases. Hybrid orbitals with higher 's' character (e.g., sp) have larger bond angles (180°) compared to those with more 'p' character (e.g., sp3 with 109.5°). As 's' character decreases, the proportion of 'p' character increases, leading to smaller bond angles. Options B, C, and D are incorrect because they either misunderstand the relationship between 's' character and bond angles or suggest impossible outcomes.

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.
