Which of the following species has a lone pair of electrons on the central atom?
Correct answer: D. PCl₃
- A. CH₄
- B. PCl₅
- C. NH₄⁺
- D. PCl₃
Explanation
In Phosphorus Trichloride (PCl₃), the central phosphorus atom forms three single bonds with the chlorine atoms and has one lone pair of electrons remaining. This lone pair influences the molecule's shape, making it trigonal pyramidal.

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.
