EDTA^(4-) is ethylenediaminetetraacetate ion. The total number of N-Co-O bond angles in [Co(EDTA)]^(1-) complex ion is

Answer»


Solution :The complex `[Co(EDTA)]^(1-)` has the STRUCTURE as under :

The N-Co-O bond angles are :
(1) `angleN^(I)CoO^(I)` (2) `angleN^(I)CoO^(II)` (3) `angleN^(I)COCO^(III)`
(4) `angle^(I)CoO^(IV)` (5) `angleN^(II)CoO^(I)` (6) `angleN^(II)CoO^(II)`
(7) `angleN^(II)CoO^(III)` (8) `angleN^(II)CoO^(IV)`
Hence, total N-Co-N bond angles = 8.
