Why are multidentate ligands preferred to unidentate ligands in complexometric titrations?
Entropic advantage: [Cu(H2O)6]2+ + EDTA <==>> [Cu(EDTA)]2+ +6H2O Count your moles: Left side, 2 moles. Right side, 7 moles. The universe like to move from order to disorder. :-) Think of the occupy wall street people who would be happier if money all bundled up in some rich person's bank was distributed to the poor...The second law of thermodynamics applied to politics!
What is the definition of an anionic ligand?
all those ions or molecules are ligands which may donate one or more pairs of electrons to a metal ion forming the coordinate covalent bonds are ligands, usually they neutral or negativelycharged, all the negative ligands areAnionic ligands.
What are multi dentate ligands?
the ligands which are capable of donating two or more pairs of electron in a complexation reaction
What is weak field ligands?
The weak field ligands are those that produce a small Δ and usually lie at the left of the series.
What is trans -effect?
Trans-effect in inorganic chemistry is defined as the effect where some ligands are able to influence properties of the ground states where they are trans. It is when some ligands can be seen as trans-directing ligands.
What is ancillary ligand?
An ancillary ligand is a ligand on a chemical complex that is not directly involved in the chemistry. Ancillary ligands are often there to help stabilize a complex or contribute steric or electronic effects. Thus, activity of a complex can be tuned by adjusting the ancillary ligands, even though they are not directly a part of the chemistry that is occurring. The ligands that are involved in the chemistry are called functional ligands.
What s the difference between di and bis in nomenclature of chemical compound?
di is used for inorganic ligands or groups but bis is used for organic ligands or groups, logic is that some organic ligands also have di in their names as bis dimethyl glyximo.
Proteins that change a cell's activity when bound by a chemical signal are called a-receptors b-antagonists c-agonists d-ligands?
d - ligands.
What the similarities between enzymes and receptors?
They both have ligands.

Give the name of some strong ligands?
Define "strong"
