Linear triatomic molecules owe their geometry to their sp or sp 3 d hybridised central atoms. Well-known linear triatomic molecules include carbon dioxide (CO 2) and hydrogen cyanide (HCN). Xenon difluoride (XeF 2) is one of the rare examples of a linear triatomic molecule possessing non-bonded pairs of electrons on the central atom.
Periodic systems of molecules are charts of molecules similar to the periodic table of the elements. Construction of such charts was initiated in the early 20th century and is still ongoing. It is commonly believed that the periodic law, represented by the periodic chart, is echoed in the behavior of molecules, at least small
Some common shapes of simple molecules include: Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. For example, carbon dioxide and nitric oxide have a linear molecular shape. Trigonal planar: Molecules with the trigonal planar shape are somewhat triangular and in one plane (flat). Consequently ...
In the following example, the Lewis acidity of AH 3 molecules such as BH 3 and CH 3 + is predicted. Six electron AH 3 molecules should have a planar conformation. It can be seen that the HOMO, 1e’, of planar AH 3 is destabilized upon bending of the A-H bonds to form a pyramid shape, due to disruption of bonding.

The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°. Linear organic molecules , such as acetylene ( HC≡CH ), are often described by invoking sp orbital hybridization for their carbon centers.
