PNAS remains committed to publishing high-impact, cutting-edge research in the physical sciences. Organic chemistry largely involves the synthesis, or formation, of organic products by chemical reaction using different reactants and reagents, the substances used up during a reaction. Unlike EAS, where addition is initiated by the presence of a strong electrophile, addition-elimination can also be initiated by a strong nucleophile in the presence of a good aryl leaving group.

Analytical chemistry studies and uses instruments and methods used to separate , identify, and quantify matter. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Identification may be based on differences in color, odor, melting point, boiling point, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography , electrophoresis or field flow fractionation.
