The molecular electrostatic potentials of F2CSe demonstrate that the Se atom could play a dual role of Lewis acid and base to form a chalcogen bond with NH3 and a hydrogen bond or a covalent interaction with HX, respectively. The chalcogen bond can compete with the hydrogen bond for the ...
1. acid-base reaction is a reaction between an acceptor and an electron pair to form a covalent bond between the donor and the electron: Ag+ +2 = NH3 = [Ag (NH3) 2]+ Two The acid substitution reaction acid replaces the acid in the acid-base complex and forms a new acid-base comp...
