What is a ligand Chemguide?
The molecules or ions surrounding the central metal ion are called ligands. The nature of ligands. Simple ligands include water, ammonia and chloride ions. What all these have got in common is active lone pairs of electrons in the outer energy level. These are used to form co-ordinate bonds with the metal ion.
What is the shape of 3dxy orbitals?
The shape of the five 3d orbitals. There are two planar node normal to the axis of the orbital (so the 3dxy orbital has yz and xz nodal planes, for instance). The 3dz 2 orbital is a little different and has two conical nodes. The higher d-orbitals ( 4d, 5d, 6d, and 7d) are more complex since they have spherical nodes.
What type of ligand is EDTA 4?
hexadentate ligand
EDTA4- (ethylene diamine tetracetate ion) is a hexadentate ligand that can bind to the central metal ion by two nitrogen and four oxygen atoms. For most of the transition metals, EDTA4- forms very stable complexes.
How does cisplatin work Chemguide?
Cisplatin is a neutral complex, Pt(NH3)2Cl2. It is neutral because the 2+ charge of the original platinum(II) ion is exactly cancelled by the two negative charges supplied by the chloride ions. The platinum, the two chlorines, and the two nitrogens are all in the same plane.
What is the Orbitron?
The Orbitron is a custom car built by Ed Roth and feared lost until its rediscovery in Mexico in 2007.
Why is Dz2 orbital different?
What makes dz2 orbital so special? Although degenerate with other d orbitals, It has no nodal planes, instead it has 2 nodal “cones”. Instead of having 4 lobes, it has 2 lobes and 1 ring. Also, its electron density is prominently distributed in all x,y and z directions unlike others.
Why does the s orbital fill before the p-orbitals?
Notice that the s orbital always has a slightly lower energy than the p orbitals at the same energy level, so the s orbital always fills with electrons before the corresponding p orbitals do.
Why is EDTA a hexadentate ligand?
As we can see from the structure that it has six donor atoms , that is , two nitrogen and four oxygen atoms ( of the carboxylic acid groups ) capable of bonding to the metal atom . Hence it is a hexadentate ligand .
What is the electron configuration for copper in the p orbital?
In writing the electron configuration for Copper the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Copper go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.
What is the SP set in gaseous BeCl2?
The sp set is two equivalent orbitals that point 180° from each other. The two electrons that were originally in the s orbital are now distributed to the two sp orbitals, which are half filled. In gaseous BeCl 2, these half-filled hybrid orbitals will overlap with orbitals from the chlorine atoms to form two identical σ bonds.
What is the SP set of orbitals?
The sp set is two equivalent orbitals that point 180° from each other. The two electrons that were originally in the s orbital are now distributed to the two sp orbitals, which are half filled.
What is sp hybridization of an atom?
In sp hybridization, the s orbital overlaps with only one p orbital. Atoms that exhibit sp hybridization have sp orbitals that are linearly oriented; two sp orbitals will be at 180 degrees to each other.
