<P> A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct . A Lewis base , then , is any species that has a filled orbital containing an electron pair which is not involved in bonding but may form a dative bond with a Lewis acid to form a Lewis adduct . For example , NH is a Lewis base , because it can donate its lone pair of electrons . Trimethylborane ( Me B) is a Lewis acid as it is capable of accepting a lone pair . In a Lewis adduct , the Lewis acid and base share an electron pair furnished by the Lewis base , forming a dative bond . In the context of a specific chemical reaction between NH and Me B , the lone pair from NH will form a dative bond with the empty orbital of Me B to form an adduct NH BMe . The terminology refers to the contributions of Gilbert N. Lewis . </P>
