Which of the following is not nucleophile? Answer: AlCl₃

A nucleophile is a molecule or ion that has a lone pair of electrons available to donate to another molecule or ion. AlCl₃, aluminum chloride, is an electron-deficient molecule with its aluminum atom needing two more electrons to complete its octet. It acts as an electrophile, accepting electrons rather than donating them, making it not a nucleophile.
