# Nucleophiles¶

Nucleophiles are electron rich species that seek out a positive charge to balance themselves out

These can come under many different forms

## Anions¶

Halide Ions Hydroxide Alkoxide Hydride Carbanions

## Neutral Molecules With LPE¶

Water Alcohols Ammonia and Amines

## Species With $$\pi$$ Bonds¶

The $$\pi$$ bond is comparatively weak (compared to its $$\sigma$$ bond counterpart) and a secondary $$\pi$$ bond will be even weaker. As a result, it behaves as a nucleophile.
