How are linear pairs used in chemistry?
“Molecular geometry or molecular structure is the three-dimensional arrangement of the atoms that constitute amolecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color,magnetism, and biological activity.”
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∘. A bond angle is very simply the geometric angle between two adjacent bonds. For example, carbon dioxide and nitric oxide have a linear molecular shape.
Bent: Bent or angular molecules have a non-linear shape. A good example is water, or
H2O, which has an angle of about 105∘. A water molecule has two pairs of bonded electrons and two unshared lone pairs. Read more here ... http://en.wikipedia.org/wiki/Molecular_geometry
