How to identify a strong nucleophile

Web28 nov. 2014 · Nucleophilicity is a kinetic phenomenon. Nucleophilicity is most often defined based on the relative rate of the reactions of nucleophiles with a standard substrate in a standard solvent. For example, a standard reaction might look like: C H X 3 I → H X 2 O N u X − C H X 3 N u WebA terpene with the molecular formula of C10H16O is a waxy, white color solid known as camphor.
