Molecular Geometry and Bond Angles
- The bond angle in a molecule is determined by the geometry of the molecule, which depends on the number of bonding pairs and lone pairs of electrons around the central atom.
- For the species \([H_3]^+\), the molecular geometry can be understood by considering the electron pairs around the central atom.
- \([H_3]^+\) (protonated hydrogen) is an example of a molecule with a triangular or cyclic structure.
EXPLANATION:
- \([H_3]^+\) has a triangular structure where three hydrogen atoms are symmetrically arranged around a central hydrogen atom.
- In a perfect equilateral triangle, the bond angles are 60°, which is the expected H-H-H bond angle in \([H_3]^+\).
- This triangular arrangement minimizes repulsion between the bonding pairs of electrons.
CONCLUSION:
The correct answer is 60°.
