A Cl₂ molecule is formed by the overlap of:

Correct answer: B. p-p head-on overlapping of orbitals

  • A. s-s orbitals
  • B. p-p head-on overlapping of orbitals
  • C. s-p orbitals
  • D. p-p parallel overlapping of orbitals

Explanation

A chlorine atom has one unpaired electron in a 3p orbital. The covalent bond in a Cl₂ molecule is formed by the direct, head-on overlap of the 3p orbitals from two chlorine atoms, creating a sigma (σ) bond.
