Geometric Shape and Bond Angle

Postby Kimberly 1H » Sat Nov 10, 2018 11:15 pm

Is a molecule's geometric shape always determined by the degree of its bond angle? And what some examples of molecules whose bond angle are not "fixed by symmetry"?

A molecule's geometric shape is not always determined by its bond angle. For example, if a molecule contains a lone pair of electrons, like in H2O, the bond angle would be 120, but the geometry would be bent or angular. For NF3, the bond angle would also be 120, but the geometry would be trigonal planar. The bond angle is dependent on atoms and lone pairs, while geometry is dependent on the arrangement of atoms in the molecule.

The shape is determined by how the atoms are arranged
