Understanding the Context

What is CLF₃?

CLF₃ is a synthetic compound made from chlorine (Cl) and fluorine (F) atoms, widely studied in chemical bonding, organic synthesis, and materials science. Its unique Lewis structure explains its reactivity, polarity, and applications in chemical manufacturing.

Key Insights

Step 1: Count Total Valence Electrons

  • Chlorine exhibits 7 valence electrons
  • Each fluorine contributes 7 valence electrons, and there are 3 fluorines → 3 × 7 = 21
  • Total = 7 + 21 = 28 valence electrons

Step 2: Find the Central Atom

Chlorine, being less electronegative than fluorine, sits at the center of the molecule.

Step 3: Connect Fluorine Atoms

Each fluorine forms a single covalent bond with chlorine.

  • 3 Cl–F bonds use 3 × 2 = 6 electrons
  • 28 total – 6 = 22 electrons remain

Step 4: Distribute Lone Pairs

  • Each fluorine needs 6 more electrons to complete its octet → 3 × 6 = 18 electrons used
  • Remaining = 22 – 18 = 4 electrons → 2 lone pairs on chlorine (2 × 2 = 4)

Step 5: Check Formal Charges

  • Chlorine: 7 – (2 + 3) = +2 formal charge (highly unfavorable)
  • Each F: 7 – (6 + 1) = +0 formal charge
  • The +2 charge on chlorine indicates an unstable, intermediate structure—why CLF₃ is reactive!

Final Thoughts


Final CLF₃ Lewis Structure Summary:
