Study Notes
Molecular Geometry AXE Classification Overview
- AX2 is classified as Linear, indicating a straight-line arrangement of atoms with bond angles of 180°.
- AX3 is categorized as Trigonal Planar, featuring three bonding pairs arranged in a plane with bond angles of 120°.
- AX4 represents Tetrahedral geometry, where four bonding pairs are oriented toward the corners of a tetrahedron, with bond angles of approximately 109.5°.
- AX5 denotes Trigonal Bipyramidal structure, which has five bonding pairs with bond angles of 90° and 120° depending on their position.
- AX6 is classified as Octahedral, characterized by six bonding pairs arranged at 90° angles between them.
Molecular Geometry with Lone Pairs
- AX2E represents Bent molecular geometry (first form), with two bonding pairs and one lone pair, reducing bond angles to less than 120°.
- AX3E is defined as Trigonal Pyramidal, where three bonding pairs and one lone pair create a structure with bond angles slightly less than 109.5°.
- AX2E2 is recognized as Bent molecular geometry (second form), containing two bonding pairs and two lone pairs, leading to bond angles around 104.5°.
- AX4E is known as Seesaw geometry, having four bonding pairs and one lone pair, resulting in distorted bond angles from the ideal trigonal bipyramidal shape.
- AX3E2 is identified as T-Shaped, with three bonding pairs and two lone pairs, leading to bond angles of approximately 90° and 180°.
- AX2E3 is classified as Linear (second form), consisting of two bonding pairs and three lone pairs, commonly resulting in bond angles of 180°.
- AX5E is referred to as Square Pyramidal geometry, which features five bonding pairs and one lone pair, creating angles less than 90° and distorting ideal angles from octahedral geometry.
- AX4E2 is called Square Planar, with four bonding pairs and two lone pairs positioned opposite each other, resulting in 90° bond angles among the bonding pairs.
