Answer 1

Answers: _*) Ligand: "Any species Lionog molecules that have at least one lone pour ofere trons f that can donate its lone part of electrons to metal cation or atom is called a Ligandi - since a ligand is electron reat species, therefore it is also called as Lewis base of nucleophile.eg N Hz CM; OH ele. 27 complex: – - When a group or ligands donates its pais a electrons cie. one pair by one donar atom & ligand] to the metal caton!! coordinate bonds are formed and product is called coordination compound " Thus, a compound in which a metal cation or atom is attached to a group of liggand by coordinate bonds is called coordination compound or complex compound or simply complex. eg. (Pticle)-? [VOCNH3) TFB: 3) coordination Number ) "The atom in a ligand that is directly attached to meral atom or cettoo is called olongo atom & the numberg donor atom attached to merel otomcion is called coordination number leg-coordination nurrber & Agt in Tag (NH3), 72 is a & that of cost in [CO.
