What Is The Shape Of Clf5 Using Vsepr Theory


VSEPR theory is used to predict molecular shapes. It is based on the assumption that atoms have a tendency to arrange themselves in such a way that the valance shell electron repulsion is minimized and the distance between them is maximized. Arrangement of atoms in a molecule determines the molecular geometry. Repulsion is strongest between two lone pairs and weakest between two bond pairs.

Shape Of ClF5 Using VSEPR Theory

  • Since both chlorine and fluorine belong to the halogen group (they are group 17 elements), both their valence shells contain 7 electrons.
  • Since the difference in the electronegativities of chlorine and fluorine is not extremely high, the chemical bonds formed between chlorine and fluorine atoms are highly covalent in nature.
  • In a ClF5 molecule, chlorine is the central atom featuring five single bonds with fluorine atoms. Since chlorine has 7 electrons in the valence shell, the remaining two electrons form a lone pair.
  • As per the VSEPR theory (valence shell electron pair repulsion theory), the shape of a ClF5 molecule is square pyramidal.
