Calculate "EAN" of metal atoms in the following
(a)`Fe(CO)_(5)`
(b)`Co_(2)(CO)_(8)`
(c ) `Fe(NO)_(2)(CO)_(3)`
(d) `Fe(C_(5)H_(5))_(2)` .

Text Solution

Verified by Experts

`Fe(Z = 26)`
`EAN = 26 + 2 xx 5 = 36`

Each Co atom is shared by another Co atom So number of electrons in `Co = 27 + 1 = 28`
Each Co is joined to `4CO` molecule
`:. EAN = 28 + 2 xx 4 =36`
(c ) `Fe(Z =26)`
`EAN = 26 + 2 xx 2 + 2 xx 3 = 36`
(d) Refer to Section `7.141 b (2) and .
