Point group
C∞v — A linear molecule without a centre of inversion: a C∞ axis along the bonds and an infinite number of mirror planes containing it.
Order
∞
Operations
E, 2C∞, ∞σᵥ

Linear
Atoms
2 (H, Cl)

Symmetry elements of HCl

  • C∞ — the molecular axis: any rotation leaves the molecule unchanged
  • σᵥ (one of ∞) — any plane containing the axis
  • σᵥ (another) — any plane containing the axis

Structure

  • H–Cl 1.275 Å
  • A diatomic molecule
  • Three lone pairs on Cl
