Which of these will not show AB4 type geometry:

Correct answer: D. Group VI A element with 3 double bonds.

  • A. Group IVA element with 4 single bonds
  • B. Group V A element with 3 single and one coordinate bond
  • C. Group VI A element with 2 single and two double bonds
  • D. Group VI A element with 3 double bonds.

Explanation

This element will show AB3 type geometry with three bond pairs and thus has triangular planar 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.
