Chlorine trichloride is an interhalogen compound .
Molecular formula:
Hybridization:
Geometry: Trigonal bipyramidal
Shape: T- Shaped
Explanation:
The valence electronic configuration of chlorine atom is
Electronic configuration of Chlorine atom in excited state:
Now three fluorine atom combines with orbital of chlorine atom to form 3 bond pairs and the filled orbital consists of lone pairs, forming hybridized orbitals.
The lone pair occupies equatorial position because at equatorial position % s character is high, and fluorine atom occupies axial position having less % s character.
Structure and Geometry:
The two lone pair of electron exhibit repulsion to the bond pair which causes unsymmetrical charge distribution around the chlorine atom. The bond angle between is .
Hence, Chlorine trifloride shows hybridization with geometry trigonal bipyramidal.
