The bonding in ferrocene involves sharing of the 6 π electrons from each cyclopentadienyl ring with the iron atom. based on the electronic configuration of the iron species in ferrocene, show that a favorable 18-electron noble gas configuration is established at the iron atom.

Yes it is really occures.

Explanation:

Iron in ferrocene is Iron (II) which has 6 electrons on the d-orbitals. And cyclopentadiene provides all needed electrons to complete the 3 d level of Iron. And to go for the 4th energy level and cover that as well. Completely.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

have a great day because if you dont you and i will be sad
