17A.2 Flashcards
why are transition metals reactions different compared to normal metal
since the transition metal ion have a much smaller radii that metal ions in the same period, so they can attract electron rich species more strongly , so strongly that the these species would form a specific number of bonds (dative coordinate bonds) with the transition metal ions in a complex structure
what are dative coordinate bonds
it is a covalent bond formed between a central metal or metal ion and a ligand, in which both of the bonding electrons is supplied by ligands
what does solid wedges in bonds mean
coming out of the plan of the paper
what does stripped wedges in bonds mean
going behind the plane of the paper
the arrangements of ligands around a central metal (atom/ion) are explained by
electron pair repulsion theory
how does a complex look like
page 187
how does the abbreviation of a complex look like
[metal(ligand)n]^charge of molecule
what is a ligand
a species that uses a lone pair of electrons to form a dative bond with a metal ion
what is a complex
a species containing a metal ion joined to ligands
a complex ion
a complex with an overall positive or negative charge
what is coordinate number
the number of dative coordinate bonds in a complex
what is the ligand name of water (H2O)
aqua
what is the ligand name of hydroxide (OH)^-
hydroxo
what is the ligand name of ammonia (NH3)
ammine
what is the ligand name of chloride Cl^-
chloro
