It is a neutral ligand donating two electrons to the overall valence electron count of the molecule. Also known as triphenylphosphine; the phosphorous has three bonds to phenyl substituents as well as one bond to the main compound you are attaching it to, and a lone pair of electrons.

What is the oxidation number of Rh in (PPh3)3RhCl?
The oxidation state of Rhodium (Rh) in the complex (PPh3)3RhCl is +1. This is because each triphenylphosphine ligand (PPh3) contributes -1 charge (-3 total), and the chloride ligand (Cl) contributes -1 charge. Since the overall charge of the complex is neutral, the oxidation state of Rh is +1.
What is the charge of PPh3 when calculating oxidation states?
When calculating oxidation states of compounds containing PPh3 (triphenylphosphine), each phenyl group (Ph) is considered electrically neutral and contributes zero charge. Therefore, the charge of PPh3 is equal to the charge of the phosphorus atom in the compound. Phosphorus typically has an oxidation state of +3 in PPh3, making the overall charge of PPh3 neutral.
What is inner sphere mechanism?
The inner sphere mechanism is a type of catalytic mechanism in which the catalytic metal directly interacts with the substrate during the reaction. This involves the formation of a coordination complex between the metal center and the substrate, leading to the catalytic transformation. Inner sphere mechanisms are common in transition metal catalysis.
What is the oxidation state of pph3?
In H3PO3 each H is 1+ for a total of 3+. Each O is 2- for a total of 6-. So, there is 3+ and 6- giving a net of 3-. In order to make the molecule neutral, P must have an oxidation state of 3+.
What type of bond will phosphorus make ionic or covalent?
Phosphorous will make a covalent bond, for example in the widely used neutral ligand, triphenyl phosphorous (PPh3).Some of the covalent complexes are charged, for example phosphate (PO4-3) however the phosphorous itself is covalently bound.
What is the oxidation number of Rh in (PPh3)3RhCl?
The oxidation state of Rhodium (Rh) in the complex (PPh3)3RhCl is +1. This is because each triphenylphosphine ligand (PPh3) contributes -1 charge (-3 total), and the chloride ligand (Cl) contributes -1 charge. Since the overall charge of the complex is neutral, the oxidation state of Rh is +1.
How many electrons does the complex have using 18 electron rule Cr(n5-C5H5)(CO)2(PPh3)?
To determine the number of electrons in the complex Cr(n5-C5H5)(CO)2(PPh3), we can apply the 18-electron rule. Chromium (Cr) in the zero oxidation state contributes 6 electrons. Each CO ligand donates 2 electrons (total of 4 from 2 CO), and the PPh3 ligand contributes 2 electrons. The n5-C5H5 (cyclopentadienyl) ligand donates 5 electrons. Thus, the total electron count is 6 (Cr) + 4 (from CO) + 2 (from PPh3) + 5 (from n5-C5H5) = 17 electrons.
What is the difference between chelating agent and ligand?
A ligand is an ion or molecule that binds to a central metal atom to form a coordination complex. The bonding usually involves the formal donation of one or more of the ligand's electron pairs. A chelating agent is a type of ligand.
What is the charge of PPh3 when calculating oxidation states?
When calculating oxidation states of compounds containing PPh3 (triphenylphosphine), each phenyl group (Ph) is considered electrically neutral and contributes zero charge. Therefore, the charge of PPh3 is equal to the charge of the phosphorus atom in the compound. Phosphorus typically has an oxidation state of +3 in PPh3, making the overall charge of PPh3 neutral.
What type of ligand is nitrogen dioxide?
It is not a ligand because does not have a lone pair of electrons but nitrite NO2-1 is a strong basic or strong field ligand.
What kind of ligand is oxalic acid?
generally a bidentate, dianionic ligand
What type of transport protein is a sodium potassium pump?

Is sulphate a ligand in chemistry?
yes , it is a flexidentate ligand its denticity can be one or two
What is a backbonding ligand?
A backbonding ligand is a ligand - an ion, molecule or functional group bound to another chemical entity - which has two or more bonds to the same metal centre.
What is inner sphere mechanism?
The inner sphere mechanism is a type of catalytic mechanism in which the catalytic metal directly interacts with the substrate during the reaction. This involves the formation of a coordination complex between the metal center and the substrate, leading to the catalytic transformation. Inner sphere mechanisms are common in transition metal catalysis.
