Q. Show diffrent type of Ligands?
Ligands which contain one donor atom are called monodentate the donor atom may contain
One or more than one lone pairs of electrons. The ligands that contain two, three, four and so on donor atoms are called bidentate, tridentate. tetradentate etc., respectively. For example, .NH3, H20, F- are all monodentate ligands: CO2-3, SO2-4, H2NCH2COOH (glycine) are all bidentate ligands. Table 14.1 gives a list of anions/molecules commonly used as ligands.
A bidentate ligand like ethylenediamine is a neutral molecule but a glycinate ion, H2NCH2COO-, which is not neutral can also act as a bidentate ligand. The nitrogen atom and one of the oxygen atoms of glycinate ion can form chemical bonds with a metal ion. In order to differentiate a ligand like glycinate we call it a bidentatemo no negative ligand.

how will you test for the presence of the halogen in iodoform?
A flash separator "flashes" (abrupt increase in temperature and pressure) a liquid stream containing multiple species. Not all of the liquid vaporizes, but the vapor that does form
How to determine the mass of substance electrogravimetricaly?
The power plants at Geysers use a dry steam cycle. The steam enters the turbine at 250 o C and 30 bars represented by the point 1 in the steam h-s diagram here below. At the outlet
The total magnetic quantum numbers for d-orbital is given by: (1) 2 (2) 0, ± 1, ± 2 (3) 0, 1, 2 (4) 5 ans: 5
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
