BH3 has H-B-H bond angles of 120˚ with a shape of:
Correct answer: B. Trigonal planar
- A. Linear
- B. Trigonal planar
- C. Tetrahedron
- D. Bent
Explanation
BH3 is an AB3 type molecule with no lone pair. So, it has trigonal planar geometry and each angle is of 120°.

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.
