In which of the following the central atom has least no. of Ione pair of electrons?
Correct answer: D. PbCl4
- A. HClO3
- B. H2S
- C. H3O+
- D. PbCl4
Explanation
In PbCl4, the central atom lead (Pb) uses all its available valence electrons to form bonds with four chlorine atoms, resulting in no lone pairs on the central atom. In contrast, HClO3 has a central chlorine atom with one lone pair, H2S has a central sulfur atom with two lone pairs, and H3O+ has a central oxygen atom with one lone pair. Therefore, PbCl4 has the least number of lone pairs on its central atom, making it the correct answer.

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.
