Question

hybridisation, geometry, structure of pcl3

Answer 1

The electron arrangement in compounds is determined by the Lewis structure of the compound. From the Lewis structure, we can use the electron pair arrangement around the central atom to predict the molecular geometry of the compound.,

The molecular geometry of PCl3 is trigonal pyramidal.

The Lewis structure of PCl3 is:





VSEPR is short for ''valence shell electron pair repulsion'', which helps us predict the molecular geometry of molecules. We count the total areas of electron density around the central atom and how many of them are lone pairs. A VSEPR chart tells us the molecular geometry based on this information. Since there are four regions of electron density around phosphorus (three bonds and one lone pair) indicates this molecule is trigonal pyramidal.

Answer 2

sp3, triagonal pyramidal geometry
