Calculate the Effective Atomic number of...

Calculate the Effective Atomic number of Mn is `Mn_(2)(CO)_(10)`.

Text Solution

Verified by Experts

Structure of the compound : `(CO)_(5)Mn-Mn(CO)_(5)`
Number of electrons in Mn = 25 (Atomic Number ). Number of electrons gained from 5 ligand molecules `=2xx5=10.`
Electrons from `Mn-Mn` bond = 1.
`therefore" "` The Effective Atomic Number (EAN) of Mn = Atomic Number of Mn - Oxidation Number (State) on `Mn+2xx" Number of ligands "+1" (Electron from Mn - Mn bond)"`
`=25-0+2xx5+1=25+11=36`
