Total number of electron pairs present in the valence shell of central atom in water are

Correct answer: C. 4

  • A. 2
  • B. 3
  • C. 4
  • D. 5

Explanation

the total number of electron pairs in the valence shell of the central atom (oxygen) in water is:2 bonding pairs (with hydrogen) + 2 lone pairs = 4 electron pairs.Therefore, the total number of electron pairs present in the valence shell of the central atom in water

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.
