Calculate the EAN of the metal in the following complexes and compare it with the atomic number of nearest noble gas.
(i) `[AuCl_(2)]^(-1)`
(ii) `Fe(C_(2)O_(4))_(3)]^(3-)`
(iii) `[Cr(H_(2)O)_(4)NH_(3)]^(2+)`
(iv) `[Zn(OH)_(4)]^(2-)`

Text Solution

Verified by Experts

(i) `[AuCl_(2)]^(-)` : EAN `= (79-1+2xx2) = 82, Xe(Z=86)`
(ii) `[Fe(C_(2)O_(4))_(3)]^(3-)`: EAN `= (26-3 +2xx6)=35, Kr(Z=36)`
(iii) `[Cr(H_(2)O)_(4)NH_(3)]^(2+)` : EAN `= (24-2+2 xx 6) = 34 , Kr(Z=36)`
(iv) `[Zn(OH)_(4)]^(2-)` : EAN `= (30-2+2xx4) = 36, Kr(Z=36) `
