Definitions:

Anionic Nucleophiles

Negatively charged species that donate an electron pair to electrophiles in chemical reactions.

Polar, Aprotic Solvents

Solvents that possess a dipole but do not have an acidic hydrogen, often used in organic synthesis.

Nucleophilicity

A property of chemical species that reflects their tendency or ability to donate an electron pair to an electrophile to form a chemical bond.

Basicity

A measure of the ability of a compound to accept protons.
