chemistry,like every day live, takes place enormously in three diemensions. stereo chemistry embrces the spatial aspect of chemistry and can be considered in two parts. the first deal with the shapes and properties of mainly three dimensional molecules and involves aknowledge of the terms conformation ,configuration and chelarity,which spicify compounds.
the second aspect deal with reactivity and include prefered or obligatory directin of approach of reagent and also the consequence for the natural of product .we can say that expect for spherical reactant as hydrogen positive ion.....ect of one moleculeor ion toward another.
