catalysts Flashcards
what is a dative covalent bond
both shared electrons originate from one atom in the bond
what is a transition metal complex
a compound made of transition metal ion bonded covalently to ligands
what is meant by classification for ligands
ligands can be classified according to the number of atoms they use to bond to a transition metal ion
eg monodentate = 1 atom
what is meant by coordination number
the number of bonds formed by the transition metal ion
what is meant by coordination number
the number of bonds formed by the transition metal ion
what are the ligand names of the halogens
add an ido (chlorido, iodido, bromido)
what is the ligand name for oxygen
oxido
what is the ligand name for water
aqua
what is the ligand name for ammonia
ammine
what is the ligand name for cyanide
cyanido
what is the ligand name for hydroxide
hydroxido
what is the ligand name for carbon monoxide
carbonyl
when naming a transition metal complex, what order do you name things in
- pos before neg
- ligands are named alphabetically before the metal ion
- prefixes used for multiple ligands
- if the complex has a negative charge, end it in ate
- charge is a roman numeral after the transition metal name is given
what is the name for a negatively charged copper ion
cuprate
what is the name for a negatively charged iron ion
ferrate
