1. A coordination complex’s core atom/ion is also known as ________ a) Bronsted-Lowry acid b) Lewis base c) Lewis acid d) Bronsted-Lowry base
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, NH3 is a Lewis base, because it can donate its lone pair of electrons.
