Question

What are some examples of nucleophiles and strong bases?

Answer 1

Nucleophile:

• “A nucleophile is a chemical species that form bonds by donating an electron pair.”
• The molecules/ions with a free pair of electrons or at least one pi$\left(\mathrm{\pi }\right)$ bond can act as nucleophiles.
• Some examples of nucleophiles are cyanide ion$\left({\mathrm{CN}}^{-}\right)$, ammonia$\left({\mathrm{NH}}_3\right)$ as well as water$\left({\mathrm{H}}_2\mathrm{O}\right)$.
• All nucleophiles are bronsted bases.

Strong bases:

• A strong base is one that dissociates completely in an aqueous solution.
• Some examples of strong bases are sodium hydroxide$\left(\mathrm{NaOH}\right)$ as well as lithium hydroxide$\left(\mathrm{LiOH}\right)$.
• A strong base is a substance with negatively charged oxygen, nitrogen as well as carbon atoms, and they are also considered good nucleophiles.
