Define hybridization and explain the shape of C₂H₂​, C₂H₆ and Pcl_​5 using valence bond theory.

Hybridization happens when atomic orbitals mix to form new atomic orbitals. The new orbitals have the same total electron capacity as the old ones. The properties and energies of the new, hybridized orbitals are an 'average' of the original unhybridized orbitals. Is called as hybridization...
