AB4 type with no lone pair; this geometry enables the formation of which shape of molecule?
Correct answer: B. Regular tetrahedron
- A. Trigonal
- B. Regular tetrahedron
- C. Regular octahedron
- D. Regular pyramidal
Explanation
In AB4-type molecules, the central atom (A) is bonded to four identical atoms (B) with no lone pairs of electrons on the central atom. In this case, the geometry of the molecule is tetrahedral, which means the four B atoms are arranged around the central A atom in a regular tetrahedral shape.

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.
