Question

Molecular Geometry II The molecular geometry of a molecule describes the three- dimensional shape of just the atoms. This is in contrast to the electronic geometry, which describes the shape of all regions of high electron density. The number of regions of high electron density, or steric number, determines the shape of the molecule Part A What is the molecular geometry of a molecule with 2 outer atoms and 1 lone pair on the central atom?

Explanation / Answer

Part A

two outer atoms and one lone pair :

two outer atoms means two bond pair

so the molecule is of type, AX2E (X = bondpair ans E = lone pair) and hence according to VSEPR theory the central atom is SP2 hybridised and have a trigonal planar geometry.  

Ex : SnCl2

Part B

four outer atoms and two lone pair :

four outer atoms means four bond pair

so the molecule is of type, AX4E2 (X = bondpair ans E = lone pair) and hence according to VSEPR theory the central atom is SP3d2 hybridised and have a square planar geometry .  

Ex : XeF4

Part C

five outer atoms and one lone pair :

five outer atoms means five bond pair

so the molecule is of type, AX5E (X = bondpair ans E = lone pair) and hence according to VSEPR theory the central atom is SP3d2 hybridised and have a square pyramidal.  

Ex : IF5
