For uranocene, the correct statement(s) is/are:(I) Oxidation state of ...
Uranocene is an organometallic compound with the formula (C8H8)2U. It is a sandwich compound consisting of two cyclooctatetraenide (COT) ligands bound to a uranium center. Let's go through each statement and check whether it is correct or not.
Oxidation state of uranium is 4
The oxidation state of the uranium in uranocene is +4. Each cyclooctatetraenide ligand has 8 carbon atoms, each of which donates one electron to the uranium center, resulting in a total of 16 electrons. Uranium has 4 valence electrons, so the total number of electrons in the complex is 20. Since the complex is neutral, the oxidation state of uranium is +4.
It has cyclooctatetraenide ligands
As mentioned earlier, uranocene has two cyclooctatetraenide ligands. These ligands are cyclic and planar, with 8 carbon atoms arranged in a square. They are aromatic due to the delocalization of electrons around the ring.
It is a bent sandwich compound
Uranocene is a bent sandwich compound, meaning the two cyclooctatetraenide ligands are not parallel to each other. The angle between the two ligands is around 130 degrees. The bending is due to the steric repulsion between the ligands.
It has 2 charge
Uranocene is a neutral compound, so it does not have any charge.
Therefore, the correct statements are I and II, i.e., the oxidation state of uranium is +4, and it has cyclooctatetraenide ligands.
