What is the order of nucleophile strength in organic compounds?

Examples of nucleophiles are anions such as Cl , or a compound with a lone pair of electrons such as NH3 (ammonia) and PR3. In the example below, the oxygen of the hydroxide ion donates an electron pair to form a new chemical bond with the carbon at the end of the bromopropane molecule. The bond between the carbon and the bromine then undergoes heterolytic fission, with the bromine atom taking the don… WebThis video explains what factors to consider in determining whether something is a strong nucleophile or a weak nucleophile.
