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.
4 CO is a pi acceptor ligand Why?
Carbon monoxide (CO) is a pi-acceptor ligand because it has a lone pair of electrons on the carbon atom that can donate into vacant d orbitals of the metal center. This interaction results in backbonding mechanism where there is electron transfer from the metal to the ligand, leading to the formation of pi bonds. This enhances the stability of the metal- CO complex.
What is the role of cobalt in the compound Co(SCN)42-?
Cobalt in the compound Co(SCN)42- acts as the central metal ion, surrounded by four thiocyanate (SCN) ligands. This coordination complex is formed through coordination bonding, where the cobalt ion interacts with the ligands to create a stable structure. The cobalt ion's role is to provide a positive charge and coordinate with the surrounding ligands to form a stable compound.
What is inner metallic complex?
Some ligands such as acetyl acetonato, glycine etc. have both neutral donor and anionic (acidic) groups. Co-ordination number and oxidation state i.e., charge on metal ion gets satisfied simultaneously when metal ions are co-ordinated to such ligands. Complexes so formed are called inner metallic complexes or only inner complex. Examples of inner complexes are:[Co3(gly)3], [Co(acac)3], [Cu(gly)2] and [Cu(big)2]whre, gly = glycinato, acac = acetyl acetanato and big = biguanido.
How do you calculate Oxidation no. of Co(NH3)6?
To calculate the oxidation number of Co(NH3)6, first identify the oxidation number of ammonia (NH3), which is -3. Since there are six ammonia molecules surrounding the cobalt (Co) atom, the total charge contributed by the ammonia ligands is -3 x 6 = -18. Since the overall charge of the complex is usually 0, the oxidation state of cobalt (Co) in this complex is +3 to balance the charge.

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.
Define complex ion and give two examples?
A complex ion is a chemical species consisting of a central metal ion bonded to ligands. Ligands are molecules or ions that donate electrons to the metal ion to form coordinate covalent bonds. Two examples of complex ions are [Cu(NH3)4]2+ (tetraamminecopper(II) ion) and [Fe(CN)6]4- (hexacyanidoferrate(II) ion).
Why does fluorine show highest co-ordination number of the element?
Well, the question is wrong. Fluorine shows only one co-ordination number. Each fluorine atom will form only one bond as it requires only one electron to complete the octet. The highest coordination number is generally shown by elements belonging to the f-block (the lanthanides and the actinides). As a ligand fluorine does cause other elemnts to exhibit high coordination numbers - it is a small ligand and this why more can be placed around a central atom.

What is the metal carbonyl?
A metal carbonyl is a complex compound consisting of a metal atom bonded to one or more carbon monoxide (CO) ligands. These compounds are known for their unique bonding properties and are often used in various industrial processes and as catalysts in organic chemistry reactions.
