What substances is an elecrton pair donor?

Electron pair donor is a chemical species that can supply electrons to a dative bond. They are also known as Lewis bases or nucleophiles.

Some common electron pair donors include:

* Ammonia (NH3)

* Water (H2O)

* Hydroxide ion (OH-)

* Amine (RNH2)

* Ether (ROR)

* Carbon monoxide (CO)

* Nitric oxide (NO)

These substances can all donate a pair of electrons to a dative bond because they have at least one lone pair of electrons. A lone pair of electrons is a pair of electrons that are not involved in any covalent bonds.

Electron pair donors are important in many chemical reactions. They can be used to form new covalent bonds, to donate electrons to metal ions, and to act as catalysts.
