regioselectivity
This term is a highly specialized technical descriptor used almost exclusively within organic chemistry and molecular biology. It describes the spatial preference of a chemical reaction, specifically when a reagent attacks one particular atom or bond over another in a molecule that has multiple potential reaction sites.
Because it refers to a specific chemical property or a measurable degree of preference, it is treated as an uncountable noun. It is typically modified by adjectives such as high, low, or absolute to indicate the efficiency of the reaction's directional preference.
