Formation of Hydrogen molecule according to VBT theory involves overlap of _ ?
Correct answer: A. 1s orbital
- A. 1s orbital
- B. 2s orbital
- C. 2p orbital
- D. 2px orbital
Explanation
The formation of the hydrogen molecule can be explained using the Valence Bond Theory. According to VBT, atoms form bonds by sharing valence electrons. In the case of H2, each hydrogen atom has one valence electron in its 1s orbital. When the two hydrogen atoms approach each other, their 1s orbitals overlap to form a molecular orbital that is shared between the two atoms. This molecular orbital is called a sigma (σ) bond.

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.
